Earlier quoted context omitted.
The current socio-political climate is actually making this analogy less US-centric by the day :( edit: I'm specifically referring to people losing their jobs and similar retaliations due to being on the left, or making public statements that the current administration and supporters don't like.
It didn't start when it was people losing their jobs on the right? Brandon Eich's political donation comes to mind.
Over the past few decades, and especially since about 2008, "the right" has become the refuge for every kind of bigotry (especially, though not solely, in the USA). Trying to defend that bigotry by crying about political neutrality is...well, to be polite I'll just say it's pretty ugly and leave it at that.
