Why was the occupation of government buildings in Ukraine a very good thing in January, but it is a very bad thing in April?

I'm confused. A few weeks ago we were told in the West that people occupying government buildings in Ukraine was a very good thing. These people, we were told by our political leaders and elite media commentators, were 'pro-democracy protestors'.

The US government warned the Ukrainian authorities against using force against these 'pro-democracy protestors' even if, according to the pictures we saw, some of them were neo-Nazis who were throwing Molotov cocktails and other things at the police and smashing up statues and setting fire to buildings.

Now, just a few weeks later, we're told that people occupying government buildings in Ukraine are not 'pro-democracy protestors' but 'terrorists' or 'militants'.

Why was the occupation of government buildings in Ukraine a very good thing in January, but it is a very bad thing in April? Why was the use of force by the authorities against protestors completely unacceptable in January, but acceptable now? I repeat: I'm confused. Can anyone help me?
The anti-government protestors in Ukraine during the winter received visits from several prominent Western politicians, including US Senator John McCain, and Victoria Nuland, from the US State Department, who handed out cookies. But there have been very large anti-government protests in many Western European countries in recent weeks, which have received no such support, either from such figures or from elite Western media commentators. Nor have protestors received free cookies from officials at the US State Department.

Surely if they were so keen on anti-government street protests in Europe, and regarded them as the truest form of 'democracy', McCain and Nuland would also be showing solidarity with street protestors in Madrid, Rome, Athens and Paris? I'm confused. Can anyone help me?
A few weeks ago I saw an interview with the US Secretary of State John Kerry who said, “You just don't invade another country on phony pretexts in order to assert your interests.” But I seem to recall the US doing just that on more than one occasion in the past 20 years or so.

Have I misremembered the 'Iraq has WMDs claim'? Was I dreaming back in 2002 and early 2003 when politicians and neocon pundits came on TV every day to tell us plebs that we had to go to war with Iraq because of the threat posed by Saddam's deadly arsenal? Why is having a democratic vote in Crimea on whether to rejoin Russia deemed worse than the brutal, murderous invasion of Iraq – an invasion which has led to the deaths of up to 1 million people? I'm confused. Can anyone help me?
We were also told by very serious-looking Western politicians and media 'experts' that the Crimea referendum wasn't valid because it was held under “military occupation.” But I've just been watching coverage of elections in Afghanistan, held under military occupation, which have been hailed by leading western figures, such as NATO chief Anders Fogh Rasmussen as a “historic moment for Afghanistan” and a great success for “democracy.” Why is the Crimean vote dismissed, but the Afghanistan vote celebrated? I'm confused. Can anyone help me?
Syria too is rather baffling. We were and are told that radical Islamic terror groups pose the greatest threat to our peace, security and our 'way of life' in the West. That Al-Qaeda and other such groups need to be destroyed: that we needed to have a relentless 'War on Terror' against them. Yet in Syria, our leaders have been siding with such radical groups in their war against a secular government which respects the rights of religious minorities, including Christians.

When the bombs of Al-Qaeda or their affiliates go off in Syria and innocent people are killed there is no condemnation from our leaders: their only condemnation has been of the secular Syrian government which is fighting radical Islamists and which our leaders and elite media commentators are desperate to have toppled. I'm confused. Can anyone help me?
Then there's gay rights. We are told that Russia is a very bad and backward country because it has passed a law against promoting homosexuality to minors. Yet our leaders who boycotted the Winter Olympics in Sochi because of this law visit Gulf states where homosexuals can be imprisoned or even executed, and warmly embrace the rulers there, making no mention of the issue of gay rights.

Surely the imprisonment or execution of gay people is far worse than a law which forbids promotion of homosexuality to minors? Why, if they are genuinely concerned about gay rights, do our leaders attack Russia and not countries that imprison or execute gay people? I'm confused. Can anyone help me?
We are told in lots of newspaper articles that the Hungarian ultra-nationalist party Jobbik is very bad and that its rise is a cause of great concern, even though it is not even in the government, or likely to be. But neo-Nazis and ultra-nationalists do hold positions in the new government of Ukraine, which our leaders in the West enthusiastically support and neo-Nazis and the far-right played a key role in the overthrow of Ukraine's democratically elected government in February, a ‘revolution’ cheered on by the West. Why are ultra-nationalists and far-right groups unacceptable in Hungary but very acceptable in Ukraine? I'm confused. Can anyone help me?
We are told that Russia is an aggressive, imperialist power and that NATO's concerns are about opposing the Russian ‘threat’. But I looked at the map the other day and while I could see lots of countries close to (and bordering) Russia that were members of NATO, the US-led military alliance whose members have bombed and attacked many countries in the last 15 years, I could not see any countries close to America that were part of a Russian-military alliance, or any Russian military bases or missiles situated in foreign countries bordering or close to the US. Yet Russia, we are told, is the ‘aggressive one’. I'm confused. Can anyone help me?
