What about calls for imprisoning people? That off limits? Because there are thousands and thousands of posts out there on leftists boards where leftists with delusions of grandeur are talking about who they are going to imprison on the right. That constitutes violence.
Since imprisoning people requires a trial by jury, and guilt beyond a reasonable doubt, it isn’t something that random people on the internet can take into their own hands. This certainly seems like much less of a problem.
