I've no idea where you live. It doesn't matter. Nobody has so far created a society free of prejudice or bias. There's nowhere you can live and be assured that you'll be treated equally regardless of race, gender or sexuality. Ironically, by insisting that there's no problem, you're telling all of those groups who experience systematic prejudice that their opinions aren't worth anything, proving them right.
