Because that’s his primary voting bloc. That last ~35% is hardline maga and won’t turn against him even if he’s raping their babies in front of them. But that was enough to get him elected, because “didn’t vote” is an even larger group.
Believe it or not, there were actually several notable “Jews for Hitler” types of movements in Germany. They were conservative Jews who supported Hitler’s conservative views more than they feared his antisemitism. They hand-waved away the antisemitism, believing that it was over-exaggerated to garner votes.
People are dumb, and many will naturally want to believe that persecution is something that happens to immoral people. If someone is being persecuted, it’s obviously because they did something to deserve it. It can’t happen to me, because I am moral and have done nothing to deserve it! Because if I accept that persecution can happen to moral people, then that would conflict with my established worldview that the world is inherently just. I am successful, and therefore I am just. And unjust things don’t happen to just people. Because accepting that the world is unjust means accepting that things like disasters, disabilities, diseases, and systemic persecution could happen to me. And that is scary, so I choose to reject that possibility and insist that the world is inherently just!
It’s to make censoring the front page easier, as /popular is sorted by sub popularity, not post popularity. /all was sorted by post popularity, weighted by how many users were in a sub vs how many interacted with the post. For instance, on /all, a post with 1k/1k active users upvoting it (a 100% upvote rate in the sub, but posted in a small niche sub) would get sorted above a post with 5k/25k (a sub with literally 25x as many active users and 5x as many upvotes, but only a 20% upvote rate).
/all has pretty consistently been a thorn in the admins’ sides, because wide scale censorship is really difficult when a tiny niche sub can hit the front page of /all. In fact, /all was fantastic for new subs trying to get off the ground, for this exact reason. If you were trying to start a new subreddit, one of your biggest sources of new users was likely going to be /all users. But it also means that wide scale censorship was difficult for the admins, because any splinter movement could start a small sub and start hitting the front page. Admins delete the sub? Users just make a new sub and repeat.
Removing /all (and forcing users to /popular instead) allows the admins to direct their focus to only the big subs. Because /popular is sorted by subreddit popularity, not weighted popularity. So small subs have basically no chance of appearing there. By pushing users to /popular, they can focus their attention on the large subs (which largely have mods who are cozied up with the admins already) instead of having to moderate a thousand tiny ones.
It’s no mistake that they removed /all right before the midterms, as they can more easily push a certain narrative if they only have to focus on a few subs. It’s also an advertiser thing, as /all doesn’t filter out NSFW or controversial subs by default, but /popular does. Advertisers tend to complain when their ads are shown alongside NSFW or controversial posts, so directing users to /popular allows them to tell advertisers that they’re not accidentally showing their ads next to porn or political posts.
