Because you now did it to yourself.
There is no “control”, there is important things to people. Hell, some things are more important than others. And genocide of your friends is one of those things.
Explain to me - why didn’t they stop the genocide (or at least the arms shipments) to Israel when they are in charge for the last four years. If you are able to do that and not sound like an absolute cynical monster, then we can talk about politics. But you can’t.
Again, you wouldn’t walk up to a gay person and try to convince them to vote for Trump because the border wall was “a good idea” (as Harris put it). They’d call you insane. They’d tell you fuck Trump because he is anti LGBT. That would still be “a single issue” for them. So why are you trying to come in here and be holier than thou, to a different group of people who have a similar dealbreaker about Harris?
