YesI think the point people need to consider is that it is not the past that matter so much, but the perceived now.
If the perceptions are based on beliefs that contradict documented historical facts, is that relevant?
Especially to those who hold them!
Perspective shapes behavior. If a person believes Republicans and/or their policies are hostile to their group, they may not support Republicans.
If a person believes that it is only a few Republicans that are hostile, but the one running for office is basically a good candidate with good policies, that person most likely vote for that candidate. The party itself is irrelevant.
