It’s important not to think that politics define individuals. In the end it’s all about the experiences one had in life. Unless someone has deep hateful bigotry or an absolute allegiance to an imperial core country (aka being a fascist) there’s no reason to not try dating and see how it works. Sometimes politics can be a point of strong disagreement and that’s not really good but I also think that any leftist must work on the “not being insufferable” skill
