I disagree, mellen. In my opinion, it's perfectly justified to not want to interact with someone over an opinion of theirs if it's particularly harsh. There are some opinions that I can't just 'agree to disagree' with and continue being comfortably friendly despite. In some cases, people's opinions
do reflect on them as people and particularly shitty ones alienate others from me on an interpersonal level, and that's fine. It's also not "denying their humanity" in any way. As an example:
I personally believe church tax in Finland should continue to be a policy, as it funds the charity work that the national church performs.
Well, person A who is a hypothetical strawman, while I personally disagree with that political opinion, I can still respect you as a person.
I personally believe all gay people are mentally ill and conversion therapy is A-OK.
...no, person B who despite being a strawman espouses attitudes I have seen real people espouse, I can't respect your opinion
or you as a person since you're dehumanizing an already-marginalized subset of humanity (that includes myself and those I care about). And I'm no worse a person for not wanting you in my life or forcing myself to look past this.
