I think the point is to distinguish ‘political opinions that I am comfortable disagreeing with people about, and can still be friendly with people who strongly disagree with me’ and ‘morally unacceptable opinions that I will neither listen to nor associate with anyone who hold them’.

There are many political opinions that I strongly believe in that I am comfortable disagreeing with people on. I believe everyone has a right to health care, and that society should guarantee basic necessities for everyone. I even feel that belief is a morality based belief. However, I can accept people disagreeing with me, and can accept that there are some strong arguments against my belief, and that good people can disagree with my position.

On the other hand, if someone believes that certain races should not have the same rights, or that women should be given less agency than men, I will not entertain that argument or accept that it is just a political dispute. That is a fundamental moral issue, and is beyond JUST politics.

Do you find leftists hate you for your position on racism? A major part of modern leftism is explicitly the belief that certain races should not have the same rights, and this is even encoded into law in many western countries, including the US (affirmative action).
