Regardless of one’s own view, it is simply unacceptable and intolerant if others are not allowed to have a different opinion. In my view, tolerance includes respecting opposing views. When that is missing, it increases polarization and bickering, and ultimately puts everyone in a bad mood.
While gay people, trans people, people of different races, and other minority groups are entitled to the same rights and responsibilities as everyone else, for most people, these aren’t the kind of things that should be preached about all the time. That constant preaching about a topic important to oneself easily backfires.
