“The gays will counter by saying that it is NOT an evolutionary dead end because they can use their sperm and egg to reproduce via in-vitro fertilization and surrogate motherhood.”

Exactly. Humans can only be reproduced heterosexually.
So believing in an undebatable fact of science is “hate speech!”
