Because critical thinking is becoming more and more vital. Without it you'll find yourself really struggling to know what to believe, and chances are you'll be duped by anything from snake oil salesmen to edgy anarchist blogs.
The fact that you seem to write tried-and-tested critical thinking skills to be "nonsense" just reinforces my impression that you really need them, and that you may not be too familiar with what they are to begin with.
I find it both funny and sad how you imagine yourself to be some sort of teacher of critical thinking while persistently failing to back up these claims about the purported bias and lack of credibility of my sources. As far as I see it you're the snake oil salesman.
Yes, following a source for a while and seeing how it holds up to fact-checking is one aspect of critical thinking. How do you know which claims turns out correct in the first place, though, without critical thinking?
By checking what third-party sources have to say about it. For example, the government claimed that the migrants were "holed up" in the squats and the children didn't get any education, the social media account of the evicted migrant group (or "edgy anarchist blog" as you so dishonestly frame it) claims that their children went to school in Exarchia. The teachers and students of the school in question then went to the media to state that the migrant children did indeed go to school there and complain that they were taken away. You know, as you were already provided a link to said media article of Al Jazeera.

No, I pointed out that teaching the ToE isn't one-sided or biased to begin with. Giving various creation myths equal time to a proven scientific fact and presenting them as equals would be biased and dishonest. Saying that facts are facts is not.
And before you go "but but Exarchia is like that!" -- no, it isn't. No such contentious political situation is, especially not while it is still ongoing. If you think it's simple and black and white, you've already lost.
Whether the migrants in question were taken to camps or not is a
fact, black and white, either they were or they were not. Whether a certain squat got attacked or not is a
fact, black and white, either it was evicted or it was not. Whether there were drugs found in the squats or not is a
fact, black and white, either drugs were found or they were not. Whether a certain embassy got its windows smashed or not is a
fact, black and white, either they were or they were not. And so on and so forth. None of your "but it's not black and white" appeals change that. Just because you don't like facts doesn't mean they stop being facts, and pulling that "one-sidedness" argument in response to facts you don't like puts you straight with the Intelligent Design crowd. Just admit that you can't back up your claims, at least there would be some honesty which could be respected.
If your next post doesn't finally include some support for your claims of my sources lacking credibility then don't expect a response anymore.
