It's not uncommon for members of the trans community to recommend cutting off family members for acts as minor as accidental misgendering, while ignoring the very real harms of social isolation.
As a trans person who's lived in a multi-generational household where only one other member knew I was trans. I can personally attest that even being closeted can be a good tradeoff for many people.
Obviously in cases of violent queerphobia the calculus will be different, but I think people chronically underweigh community and make their own lives worse for it.
There's a reason for the modern resurgence of communes, and it's not just rent. After decades of increasing social isolation we're finally coming back to the realisation that we're social monkeys.
