I switched to Lemmy when Reddit came out in support of people who abuse children. I don't even mean Trump, I just mean in general. I suggested abusers in general should face harsher penalties. They banned me for it. I said "holy shit you just did me a huge favor, apparently I was on the wrong site because our values are 100% incompatible."
I mean, there isn't even a debate. I'm not talking about people who find themselves attracted to kids. I'm talking about people who actually went out and hurt a real child facing longer, more meaningful sentences and they said nah, those people are people and need to be protected.
I've moved social networks on account of incompatible values and I think others will, too. Maybe not the majority but I think some others will. Especially as things get worse. There are networks for people who hate (like Truth Social), and networks for people who don't care (like Facebook/Insta/Whatsapp), but I think as things change, more people will care and will look elsewhere. Not everyone but some people.
I play Animal Crossing. My character has been going for 3 months as of yesterday. She has more clothes than people who live on the mainland, and a two-storey house with a basement and several rooms. She's paid off the racoon (or tanuki if you prefer) so she has no debt. As far as food, it sucks because AC is a vegan fantasy game in which meat and meat byproducts simply do not exist, but hey, the trees and crops grow every 3 days and put out more than enough food for me, the racoon/tanuki and his two nephews, his girlfriend, his ex-girlfriend and her sister, and the museum curator... oh and the ten villagers I have... to survive and thrive.
Oh, you mean a real deserted island? I couldn't. But I'm about to get off the computer and go cross some animals because they won't cross themselves! (I know that makes no sense, but neither does the name, which it's a play on. FWIW, the game's original Japanese name means something like "animals in the forest." The English name, I think, is a play on "Railroad Crossing," but it's still kind of nonsensical. Just like our reasons for playing this game...
