Don’t date conservatives, …, don’t associate with them, being MAGA should result in your total ostracization.
The closest I ever got to this with family was when I invited my folks to a semi-fancy wine and cheese kinda place and my stepdad showed up wearing an “LGBT - Liberty, Guns, Beer and Trump” t-shirt. But he was never very politically coherent - he literally complained about “socialized medicine” when they were debating the ACA during the Obama admin while sitting in a hospital bed filling out the paperwork to apply for medicare. He spent his last few years angrily bitching about immigrants, despite being a German immigrant and also bitching about any time he had to supply his citizenship paperwork in any context as though the very idea he ever had to prove his citizenship was offensive.
