won’t be fired or ostracized for it.

Wanna bet?

But you will be canceled. There are things like fediblock and block lists. Does not reaaly harm you but you get suppressed little by little.

Of course you can. You’re not free from consequences of what you said though. The internet remembers EVERYTHING. Especially on federated platforms like lemmy. Some of my first messages on newsgroups in the 1990’s are still floating around the internet.

Yeah, people will probably get angry and say mean things to you but those are just words which can be ignored. Offence is taken, not given.

This is naïve. The no one likes being insulted and downvoted for expressing their views. Sure, it doesn’t bother some people as much as others, but it’s not a conscious choice to “just ignore it,” as though that will prevent any negative feelings. The reality is that people with unpopular views stay silent to avoid these consequences, and that’s an entirely rational choice. You would do better to spend your time chastising people who attack those with unpopular views than to try to convince those with unpopular views to willingly expose themselves to online abuse.

If people are saying something you disagree with you can just say it and you won’t be fired or ostracized for it.

But you can be banned which is pretty much the online equivalent to being fired or kicked out of school.
