I didn't change the subject, I just finally removed the veil. And I do understand your argument; You've argued yourself into a bad place.
My knowledge comes from history first, and that's why so many of my posts reference it. Sometimes I want to respond to a post with some forgotten story from history, but often I'll stop myself, because no one will know what I'm talking about. Knowing history is supposed to help us avoid repeating the same mistakes, and so here I am with a history lesson.
Your argument is recycled from history, and it's been repeated in each Civil Right's battle. From Women's Suffrage it was "yeah, but women are too weak and emotional to have the vote. Everyone knows that. It's just part of the definition of a woman." Your argument is identical with, "yeah but marriage is between a man and a woman. So gay people can't be married to each other. It's just part of the definition of marriage."
Bigotry thinly veiled by "good intentions" is still bigotry. Stuttering about how definitions never change, or it's just too hard to change them is the dying wail of the old generation. You act like the bedrock of your life is precedent (it's not) and Webster's dictionary (it's not). But you're losing out to the tide of human compassion. If you're disgusted with being compared to a White Supremest, or a Sexist, then you should re-evaluate your position. Because that's how we all view it. All of us.
