can someone explain to me what is this "rule" I see a lot in posts titles? sometimes mixed with other words? I'm having a hard time to understand its meaning

I obviously don't support free verbal/physical violence.

Unless it's for defense Or against active nazis Or this kind of stuff...

oh thank you very much for your explanation! it's much clearer now :)

0:)

I tried it but it only allows very simple stuff, for instance its not possible to insert images :( but I guess i'll begin with this

We can also call it "freedom of not letting dangerous and genocidal ideology spread", but that would be more annoying to use :(

I would like to avoid using photoshop if something else is available, but thank you for the proposition!
