It's so strange because that must be what people who don't know about the term think, but those who do all know it's not really an alt-right meme at all even if it's technical origins are as such.
It's like if someone moved to America and said "Oh Thanksgiving? Never heard of it but I looked into it now, and it's a weird holiday based on whitewashing the murder of Native Americans". Technically it's true but you aren't a supporter of that or blind to that fact when you celebrate it with your family, and the insinuations about you from that are likely incorrect.
Not sure where you're getting that alt-right circle from, it's just regular Internet lingo.
Unless you consider people like Hasan alt-right too? Would be mind-blowing for sure, but hey, to reach their own.
Got popular during the pandemic, though it predates it
I think GP meant that stigmatizing the idea of a coomer is regressive and shaming, in that it's sex-negative -- if someone wants to masturbate excessively, there's nothing wrong with that, as long as it's not negatively impacting other aspects of their life. Not sure I agree with that take, but I think that's what they were talking about.
Those aren't common things to be. We have regressive and shaming names for the excessively wealthy, the excessively macho, the excessively progressive, etc.
