I totally understand that (and Im sorry for your loss). But that objectively helps the guy who would not care at all (as opposed to at least trying to put a little bit of pressure) and actually encourage them to go for an even more radical “final solution”. Voting is always picking the least evil. The US system simply does not allow you a serious choice - it would be better to direct your anger against that system, instead of against the least evil of the real options.
