You can savely say that left tendencies have been in charge of the agenda setting in most of western society. And Campuses are mostly politically left, look at student movements and most professors. In Germany a mathematics prof was fired because he let his students calculate how likely it is that a terrorist is also a muslim.
As a student at a German university I can promise you there are most certainly right wing student movements and clubs. At my University there are at least 2 that are known for being right wing (not extremist, just very conservative) and 1 more is being rumoured to be too. I have to agree that there are more left leaning organisations around, though.
I don't know the circumstances of that incident with the teacher but whatever the reason, doing something like that (giving such a task to students) is just absolutely tasteless.
Again, those groups (or lesser groups) are (in my subjective view) in charge of agenda setting, or atleast the public media output follows a "left" mainstream. Since we are on a international forum this is hard to proof for all countries, so I can only talk about German media. For example, media outlets were asked to not talk about the heritage if they reported any sort of crime related to immigrants.
This, again, is NOT the case for all media outlets. You can see tendencys though.
Who asked the media to not publish heritage? Leftist extremists? Certainly not. It was probably the government to prevent any more right wing hate crimes like there have been a ton of in Saxony with the refugee camp burnings.
There is a difference between actually discussing different opinions (wich is sometimes happening here) and outright refusing to listen to someone because you assume you have the moral highground(wich is happening here most of the time, from BOTH sides).
Unlike you most right wing people are brainwashed into oblivion and refuse to listen to any arguments. I very rarely encounter left wing extremists on the internet but they are the same, I guess the internet is just an outlet for all the hate people don't dare to let lose in public.
I know its a shitty personal experience argument, but every time I try to talk about the problems that occur with bringing over a million immigrants into your country in less then 2 years I get called a nazi or im being "intolerant".
That is unfortunately a very German problem, undoubtedly fueled by our past. Yes there are problems with the way the situation was handled, but I am proud of our chancellor, that she as the only western leader stood up for the principles, morals and values the EU stands for. Sure we could have closed our doors and not let people in, after all it's not our problem if they all die in their puny conflict down there, right? But that goes against everything we have been trying to achieve in Europe for the past 70 years.
I have talked to refugees, my parents are taking care of a family from Afghanistan/Pakistan who fled here, because they married against their family's wishes. The husband got beaten up, shot and stabbed multiple times (nearly deaf and blind, broken bones all over, permanent limp). And no they were not poor, they owned a general goods store before they fled the country, but what does money mean if you have to fear for your and your family's safety. If we are closing the gates to people like them who have done nothing to deserve their fate, how can we say we are for human dignity, for the equality of men, for liberty...
Sure there are problems and yes, there will be even more problems in the future for Germany because we showed empathy and "loved our neighbour". But I rather have these problems than become an intolerant (and yes I think the word is applicable here unlike in your case) society like Hungary or Poland who turn away from the values of the western world to "protect" what's left of their shitty nationalistic countries.
Yeah sure, the left is just more intelligent than the right! Not like the left EVER ignores facts right?! *stares at obvious issues with mass immigration*
Look at the the people who vote AfD and march with Pegida and you have your answer.
