The example given by the person you're replying to seems, to be understated about it, to be in a bit more complicated of an area than "just don't talk about it and things will be fine." If Bob and Alice have significant disagreements about health care policy and taxation, they can probably still get along by just not talking about it. If Bob believes Alice should be put to death because she's a transwoman, that could, you know, lead to a bit of workplace tension even if they don't have casual conversations at the La Croix cooler over how he thinks she should be stoned and she thinks she shouldn't.
