What's the statement being disagreed with? This is just "all political opinions are valid" bullshit. There are some truly horrific political standpoints out there.
I got a 30 day suspension from /r/news for calling Antifa “a violent organization”. Got down voted to hell and called a Nazi sympathizer… I’ve only ever voted Democrat.
And antifa can be violent, though it's not really an organization. Wikipedia describes it as a movement. And given the fact that fascists have ruined every country where they took power, violence against them is wholly justified.
4channer likely leaving out the part where it wasn't "everyone who disagrees with me" but actually just "Nazi scum" and he was offended. Nazis love to play the victim card publicly while wishing death on minorities in private.
Except Reddit bans you if you so much as suggest someone stubs their toe. The rules against "advocating violence" have become so broadly interpreted in the last few years.
Lemmy is significantly more tolerant of this kind of posting
