I’m not sure you know what an opinion is. It is a thought basically that isn’t 100% proven true. A view point or belief. These things can be debated. I myself am transgender and if someone did not agree or understand what I am, I feel we can sit and have a calm discussion about it. Whatever their opinion in the end is is on them. As adults, I do feel we can share our thoughts and beliefs and maybe even change minds for the better. It isn’t impossible. Also there are other issues in the world like abortion, homophobia, religion, etc. Racism isn’t the only problem. Last thing, your use of “blind date” was not ablist. Ableism from what I read is the discrimination against disabled people. Don’t be hard on yourself.
My opinion on this is, it is a nice thing to hope for but I have my doubts it is that easy. I do believe there are people who have opinions who will openly discuss things with others with different opinions.
