As I said below I do not find it useful at all to try to list out the views that are not tolerated as there is no way that you can reduce a huge population groups opinions into neat categories, people can hold both conservative and liberal opinions as well as everything outside those at the same time, and I believe doing so would distract from the real conversation which is the intolerance.

There are also plenty of leaked examples of how people with other opinions are treated to even shock me that generally agree with the predominant view, and I encourage you to look it up and form your own opinion.

> Why is it sad? They get to go back home instead of on the other side of the planet from the place they grew up, and they don't have to give up nearly as much to do it.

As an immigrant myself I can tell you that leaving my network and life here would come at a huge cost. There are benefits of cause, especially since my home country Norway has a much better social support system. In my opinion nobody should have to do this out of fear, and that I perceive fear to sometimes be a contributing reason is what I find sad. Including the fact that I loose great colleauges that I love working with.
