I recently learned that voting on lemmy is not anonymous. Anyone can get information about who has upvoted and downvoted a post or comment.
In combination with your IP, this is a massive privacy (maybe even physical security) risk. Also, people can target you for your votes.
Sadly, this is something where I would prefer Reddit over Lemmy. Big tech scrapes data from both places anyways, at least Reddit is safe.
I feel like you misunderstand what free speech is.
Calling someone out for any opinion is part of free speech.
Makes sense
To elaborate, the ability to call someone out is literally “free speech”. The backlash you may get for said call out, in speech form, is also part of free speech.
If the government locks you up for what you said, that is not free speech.
Arguably it’s also not free speech if a community allows targeted harassment campaigns but that certainly doesn’t apply to random single comments and moderators exist to hopefully prevent or minimize that.
