There's a reason why the feminist saying "the personal is political" is so threatening. Because it denies precisely the reasoning seen above and elsewhere in this thread.
Conservatives often complain about progressives ending relationships and friendships over "politics". Because they want to draw a hard line between the two, where as long as they behave civilly to people's faces, it doesn't matter when they vote to make the same people's lives materially worse. Because "politics" is something... I don't know, abstract?
