First of all, props for shipping this! It says you're only 18 so great work!
I think that people are taking issue with this though:
> Taking aside what people might think about diversity, we've seen that ideologies radicalize when we are only surrounded by like-minded people, usually from similar backgrounds
You've classified people based on gender and sexual orientation but that doesn't actually mean they have different backgrounds. 99% of my upper middle class friends have nearly identical opinions (very liberal for the record). It doesn't matter if they're men, women, lgbqt+... I suspect you'd get more actual diversity by looking for people (regardless of gender or sexual preference) who don't live on the coasts or in major cities.
