So your defense of say US slavery is that slaves in other parts of the world who had it worse? That's curious. I guess you would take it one step further and say gays and transgenders today should just be glad they aren't slaves? Here is the thing. You define erosion of freedoms as having to tolerate LGBT people and treat them as equals. Most of us do not. That's why the term progressive is good. It come from progress. And btw, if you are worried men who think they are women hanging out in the men's rooms to pick up other men, don't you want them to actually use the female restroom? Won't that solve your worry?
