Do you think it's easy to be supportive of the current US president, supportive of Brexit and sceptical of climate alarmism while working in tech (or in academia, for that matter)? I do not find it easy at all.
It's a different thing if you want to actively talk about it, but then you need to be ready to receive the responses.
Though openly supporting racist, anti-immigrant policies in a field with so many talented immigrants may actually be a unique challenge. Promoting policies that attack your coworkers seems like it would alienate a lot of people, at least if you expect to be able to share your beliefs about how people like them shouldn't exist.
There is evidence that current eco-policies are pushing industry and hence economic power into the hands of an insane totalitarian regime and nobody seems to be discussing possible outcomes of that.
There is evidence that H1B has been abused by body shops for a very long time now and nobody seemed to care until some Americans really got pissed and partisan about it.
