Entirely depends on the disagreement. There are instances and communities where bigotry is tolerated. I do not frequent them. I would very much like the mods of the communities I use to continue banning people that disagree with them about things like basic human rights and hate. People are free to share their opinions on basically anything most places on the fediverse. Just don't be a dick, you should be fine. If the "freedom of speech" you're looking for is the freedom to be racist, homophobic, transphobic, or generally hateful, you'll probably be disappointed.
