Well, it says that openly harassing users is against the rules. So as long as expressing a non far left wing opinion isn't considered as harrassment by anyone, that's fine, but when you've got people like this:

McScx    @mcscx@socialistgeek     18h
@socialistgeek please point @knuthollund to accounts of reactionaries, far-right, Trump supports & anti-social-justice people on quitter-no

Yes, let's remove anyone who disagrees, even if they are not harassing anyone directly.
