Interesting post. It is an opinion I have heard a few times before, and while I view the overall idea as good natured, I also would disagree in a lot of ways.
Being a firm believer in the fact that everybody is entitled to their own opinion, I try my hardest to respect others' thoughts. However, I would say, there is a line. While hate is, yes, an opinion, I will not stand to respect it. Especially as a queer person, I will not stand to respect opinions which wish for my, or any other human being's death and deprivation of rights. Hatred on the basis of someone's identity (an identity which is hurting nobody, unlike the alt-right) is never acceptable, and reflects a vast amount about someone's character. I could never be friends or maintain a relationship with somebody who judges people based on their skin colour, sexual orientation, gender identity, etc. That disgusts me to my core, and of course, you have your right to disagree, but I have my right to be outraged at the discrimination and awful, awful treatment minorities have faced for so, so many years.
I thank you for sharing your thoughts. Let me put it to you this way then. Imagine a world where you do not engage with that person and they continue living their life furthering the cause you so despise. Now imagine a world where you do engage with this person and, just maybe, you manage to change their mind. Which one of those two worlds do you think are better of?
I understand there are some people out there who believe in vile doctrines, but the way to change a person is to continue treating them with respect, even in the face of their hatred. Eventually, they will begin to question their behaviour and feel guilt about the way they are treating you when you do not reciprocate.
I don't know. It's just the way I see it.
