I’m partly replying because you mentioned social anxiety… and didn’t want to leave you hanging.

The other thing is about up/down votes. With the fediverse particularly votes seem to be affected more where you speak than what you say.

Each instance and more so community has a distinct flavour. A couples meme won’t work on a femcel comm. A new publication of a bible would bomb with the atheists but might be a hit with the book enthusiasts. So don’t worry about votes… we’re all complete strangers and our opinions, whilst interesting, are just opinions.

You’ll be fine.
