I have a theory about the tendency for generation Z to lean right.
In psychologically, anything that is repressed has a likelihood of coming back with a vengeance. Zoomers have been the most coddled generation to date, and were raised in a more feminine fashion lacking competition. Likewise, whites of generation Z have been told they are racist and to feel guilt because of their race. So, now that they are coming of age, you get many zoomers on the right. They are pushing against what they have been told all their lives. They are waking up. This gives me hope.
