I loathe anyone who supports Trump in 2020; if there is any such in my acquaintance, I disassociate from them immediately, permanently and irrevocably. In 2016, one might have hoped for something from Trump, but now, in 2020, there can be not a tiniest bit of doubt any more about what Trump is, and there can be no doubt about what people who still support Trump are.
Added later - there is a point where things go beyond being merely political differences that correctly should not have any impact on personal relationships and instead enter into our fundamental conceptions of ourself as ethical human beings. As I've written in a comment below, I cannot reconcile support for Trump and being a person with basic decency.
