I don't know if it pertains to whatever the dispute is, but many people try to hide their exceptionally shitty ideas into the "oh it's just different" category. There's a gamut of regular bickering that occurs all the time and christians/republicans/trumpers have stepped well outside of that gamut in recent years. At some point, these really shitty and hateful ideas are no longer "just different" and not just worthy of disrespect, but disrespect is actually the correct course of action, because entertaining the idea of something like bigotry with a straight face is, in itself, lending credibility to bigotry, and you just can't allow that to happen.
