So, again, because they don't "automatically" broadcast their sexuality when they walk into the room, it's their fault if it becomes known and they suffer ill will because of it. That is exactly what you are saying. It's an equivalent thing in the sense that neither is a choice. You're born with your sexuality the same way you're born white, black, Asian, or whatever. Just because one is obvious visually while the other isn't, it doesn't make it any different. No matter what sense you are using to determine a difference, it's still prejudice to discriminate against a person because of it. A "visual" prejudice is no difference than one brought about based on what you hear about someone through whatever outlet. One may be easier to determine at a short glance, but that doesn't make it any more or less idiotic, hateful, or understandable. In any case, it's not the fault of that person that they were born that way, and just because one can hide it, doesn't mean they should ever have to just to avoid baseless, thoughtless hate.
