I haven’t seen the bombers name, picture, or manifesto. I’m going to go out on a limb here and say that this was a terrorist and a bad person. I promise not to change my mind about this tomorrow when more details about the bombers background are known.
There are, and my state would have banned those too it they’d heard about them when they were banning RCV. They weren’t making principled objections like monotonicity failures. They likely noticed that most of RCV’s loudest advocates were from the wrong party (and some of the were the wrong color too!), and figured that was a good enough reason to shut it down.
