For years and years, the right-wing has been calling the left traitors, said they were intentionally destroying America, spread noxious conspiracy theories and have talked at length and repeatedly to "second amendment solutions." They fucking pose with AR-15s for Christmas and haven't found a shooting perp they didn't like, so long as he killed liberals.
For most of my life, the left did not go along with these framings. Now that we have a terror state under Trump, it would be a lie to turn the rhetoric down. They literally are fascists, all of them. They talk like fascists, they act like fascists -- everything is Fuhrer style government.
So of course you would blame both sides.
It is never going to stop until the GOP is made to feel consequences for it. It is no accident that their messaging has been laden with violence for years; it's literally all they have because they have no actual ideas except authoritarianism. They will return to the messaging anew, guaranteed. It's structural within the party.
