EDIT. Not commenting on it, but https://pbs.twimg.com/media/DTCqvlRXUAILVUL.jpg:large . The fact that there is open discussion on terroristic activities, and the fact that it's not removed over the course of 24 hours. What in the fuck?
Can you elaborate on what of that is the discussion of terroristic activites? Because that seems to be quiet a loose reading of the screenshot.
If I changed it up to say something like "I've never been apart of a military or war effort..." and then someone follows up with "Get in touch with your local Army of God (Christian terrorist group in the US)..." it doesn't take much reading between the lines.
The rest of it...not so much. There is a discussion of a belief "I won't say violence has no place" There is not a discussion of 'The use of intentional, indiscriminate violence as a means to create fear to achieve political religious, or ideological aims'
Maybe the first part could be considered acceptable but towards the end it seems that they know what they are discussing. And even the fact that the first reply is not "Everything is not so bad, if you feel disheartened, there are numerous local community organization blah blah blah" but "get in touch with your local antifa" says a lot.
Fascism is fun: its appeal has the same root as teamwork. Joining up with like-minded people to counter a common enemy, and prioritizing ends over means, is how you get to fascism.
A handy rule of thumb is to flip the motivation in a sentence to its ideological opposite, preferably one that you don't like. If the meaning of the sentence is then abhorrent, rather than acceptable dissent, it's probably a couple of steps too far even when you agree with the sentiment.
