There was a time not that long ago, within my own lifespan, where men would recognize that there could be fundamental differences in political or religious beliefs between them, and put that aside for either pragmatic reasons, or because they bonded on much more tangible things, like hobbies, work, friendship or family. They would simply mutually agree in some unspoken manner not to talk about those political differences, and get on with other things.
I know it's really hard to believe, but that's how it was, and honestly, when society is functioning properly, it's how men should be. In fact, not being able to do it would be seen as something of a character flaw.
