I mean the baseball game thing was pretty unprecedented and fortunately hasn't become a trend.
Its not like other violent events. There was an intent to kill. The man definitely wanted to kill Republican politicians specifically. You won't find another event like that.
But then the original poster brings in Whoopi Goldberg being profane with Jeannine Pirro. This was not violent. No intent to kill. Neither is a politician, though one used to be a politician. There are a lot of "rude, but not violent" political exchanges every day.
To me this invites others to bring up similar events from many other angles, but, apparently not. Maybe only if they are other examples of "the right" being the victim.
