The bigger issue is most of the time people are being mislabeled as things they are not. And half the time people invoking terms like Nazi's ironically have low-grade to extreme Anti-Semitism (being seeing a lot of that on my social media feeds in recent days), and other bigotries of their own. A good metric is how much their rhetoric seems driven by cruelty rather than compassion and empathy (empathetic people dislike bigotry because they don't want anyone being dehumanized), some people just want an easy excuse to bully (whether their target deserves it or not). I don't mind a bigot being called a bigot. I do mind people abusing those kinds of terms to apply it to people are not that. And there is also the blatant lying, attacks on peoples characters, and the aforementioned attempts to ruin peoples lives, destroy their livelihood and, I would argue, drive them to suicide. There is also a lot of pressure to not allow people to decide these things for themselves (i.e. there is a lot of 'either you agree with about this, or you are one of them').
