Humans have 3.2 billion base pairs. There likely has not and will never be two identically genetic humans, even identical twins are not perfectly identical due to mutations.

Now, obviously a lot of the genetic code needs to be similar, certain parts of our genetic code needs to be similar, so it isn’t literally 3.2*10^9 factorial, but even a small fraction of that number is essentially infinite. I highly doubt there has ever been two identical humans or ever will be.

3.2 billion factorial is essentially arbitrarily large. It isn’t even really useful to think of it as a number, as we couldn’t even calculate what the number is. Visualize the largest quantity you can conceptualize, then square it until you get bored.

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.
