Since conservatives are so hell-bent on teaching kids to exclude people, we should teach kids to exclude conservatives.
Nearly every act of racism, homophophia, xenophobia, transphobia, misogyny, antisemitism and other bigotry ever committed has come from conservatives. It is not appropriate to keep relationships with such people.
Conservatives are not a protected class. It is perfectly legal to deny employment, service and housing based on political orientation. Marginalize hate by marginalizing the haters.
Political affiliation is not a protected class at the federal level. If a city has an ordinance against it, that is specific to that city, but in the city where I live, it is not illegal. In fact it is quite common for Assistant DA's and Sheriff's Deputies to be replaced based on political affiliation when a new DA or Sheriff comes into office where I live. I live in a major metro area in the south.
