George Will claimed consensus has been reached that homosexuality is normal. Except there PREVIOUSLY was consensus that it was abnormal. He claims the consensus has now been reached because older generations are dying off.
Science isn’t about “consensus”. It’s about facts, whether the masses accept them or not.
English is a lousy language for saying what you mean. If by "normal" you mean common, homosexuality is clearly not that. If by "normal" you mean innate and unchangeable, it may be that, but so is Down's Syndrome. And while you don't mistreat people with Down's Syndrome, it is not a normal condition. If by "normal" you mean "nothing to get upset about," then it's a matter for consensus.
But if you could gain consensus that it was "normal" for human beings to eat their own vomit, that still wouldn't make it good.
Many behaviors are “normal” but that doesn’t make them acceptable. Selfishness is normal also. There are many other examples.
