It's not a choice between inaction and action, it's a choice between making a lasting difference and adding to the problem.
I contend that I have done more to help our society by showing 3 people that tolerance, peaceful coexistence, and acceptance are possible than anyone ever has by throwing more wood on the hate fire. We aren't working towards normalizing or ensuring essential services aren't denied to anyone, we are deliberately and meticulously sending the message that as long as you believe differently from me, you will never have peace.
I don't need to rely on "what if", because I can rely on the results I see in front of me. There is no hypothetical, no idealism, no sanctimonious preaching, we are actually sitting right here, getting along. I am friends with their families. They are with mine too, and my old man has a four year classical seminary degree and has a leadership role in our southern Baptist church. The bisexual one calls my mother "Mom #2", and lived with us for like 6 months. One of my group is hardline republican, the other hardline liberal, the other is... I think independent? I'm actually not sure. He has liberal leanings.
I have yet to hear anyone explain to me why they cannot reach across boundaries the same way we have. Why they will not? Sure. I'm tired of hearing people talk about polarizing their own views against others' like they are somehow being forced to do it, like they are some kind of tragic protagonist fighting the good fight. You hate them because they have different beliefs. The names don't matter.
