So, insensitivity and equality
So I give you this to think on; we loath and despise sin and wrongdoing because it hurts people. Stealing something takes something else away from a person or people. Murder removes life, something precious that can never be replaced entirely. Adultery causes emotional harm to the victim of it, though with that it's a bit more fuzzy. In general, when we think something is a sin, it's because there's a negative consequence to it. How you weigh out something that causes both positives and negatives is your own personal business and philosophy.
So I must ask, to all those who think that particular sexual orientations, something you can't even control, but even assuming you could control, is wrong and a sin, what negatives does it cause? What harm is done to us as a species?
Bonus question. How wrong is it that, by confronting someone over an act that causes no wrong, you yourself cause wrong by emotionally scarring that person? Perhaps you didn't mean to, perhaps you tried to be nice, and that can be applauded, but it's the straw that breaks the camel's back many times. You yourself may not cause harm, but combined with others, that constant act of telling that they are doing wrong, is harmful.
