Topic: Serious Discussion / Would it be immoral to have sex with aliens?
If aliens came here, I think they would be much smarter than us, and by extension “capable of choice.” Also, different species have sex all the time. Mules are donkeys and horses, and we don’t see anything wrong with that. So no, there would be absolutely nothing wrong with it. You may not be the most liked person afterwards, but that’s other people’s views.
