Dude. No.
The idiot that committed the political violence that you tried to hold up as a "BoTh SidEs" was on the same side as the idiot he tried to kill.
90+% of the political violence in this country has been committed by the same party.
Whatever you think you're trying to do is only helping the fascist idiots.
ETA: also, "No true Scotsman" is a MASSIVE stretch for this. Again, statistically violence is almost entirely owned by the Republican party. You're 100% trying to "both-sides" this.
Actually, second edit: The fact that you completely shifted you goalposts after I pointed out that it wasn't the left that tried to assassinate Trump tells me everything I need to know about you. That was your whole point - and it's completely false.
