No, they didn’t get their transphobic rhetoric from “old ass conservatives”, because they aren’t all old. You also don’t have to “hang around old racist conservatives”, as you implied in one of your other replies, because the Internet gives alt-right influencers a platform which even teenagers have access to. Many of those influencers aren’t even in their 40s, Ben Shapiro or Andrew Tate for example, and they are just the tip of the iceberg. Of course the Internet isn’t necessarily the cause for bullying, but there is a big leap from bullying to murdering someone, and being confronted with alt-right propaganda on perhaps a daily basis does change you and your views on certain minorities or communities, especially as a teenager. And I know that for a fact, because I was part of that shithole for some time during my teenage years. Someone who is more susceptible to that rhetoric could very well be pushed over the edge by that. Intolerance isn’t a thing that just comes naturally, it’s driven by the environment you grow up in or that you surround yourself with, be it in the real world or on the Internet. Nazis didn’t naturally think that it would be okay to just kill certain minorities, it was years of propaganda that altered their views to somehow justify that thinking, even from a young age in the Hitlerjugend, and it clearly worked. It’s the same shit all over again, just less organised. Why else do you think they specifically targeted a trans* person? And why else would they be so extreme to even kill her?
It is EXACTLY because of conservatives.
The Internet is international, especially so if you share a native language like the UK and the USA do. My native language isn’t English, but even I got into their politics, or rather culture wars. And girls take part in that shit too. Mostly focused on different topics, but still.
One of the most prominent figure in the anti-trans movement is J. K. Rowling, who is in fact a woman and from the UK, so that kinda disproves your points. Not to mention that she is an idol for a lot of younger people, I don’t think I need to mention why.
Oh and by the way, your insults are a little embarrassing, especially when your arguments are just blatantly false.
