people dont seem to see the difference between ending up with a party for which a good chunk of their supporters think that what Israel is doing is a genocide vs ending up with a party for which all of their supporters think not only that what Israel is doing is justified but should also do the same to all middle eastern countries (together with direct USA involvement).

I think there are two major subgroups within this group.

First one is immigrants whose families are from the middle east/Palestine who are rightfully very angry at all the world for doing jack shit about Israel committing genocide. What they have to realize is there are unfortunately only two options going ahead: 1- as it is now, maybe somewhat better in future, or 2- much worse. There is no third option that is going to come out of these elections but one where there is potential for change (potential coming from the supporters mentioned above) vs %100 chance of things going for the worse. Note that I am not talking at all about the candidates themselves at all, just the demographic that generally votes for them.

The second group is probably China or Russia fans who just want to see America suffer by getting Trump elected. These are very short sighted people with whom you cannot really have a coherent conversation with.
