I got banned from my local subreddit for saying “as an Asian we actually tend to like cars from this brand” in a politically charged post about a certain car brand. Didn’t seem very spicy to me. “If you support this brand you’re supporting Nazis” was allowed and upvoted, of course.
On the bright side that was the impetus for me to finally stop giving my valuable attention to that site.
You almost certainly are lying and were not banned for saying that.
I have mostly come to the same conclusion. I don’t go on Reddit much these days and hacker news as well. When it comes to political discussions dissent is typically challenged with various means other than debate.
