You could say the same on most of these. Like Polygamy.

"Suuuure, it's fine -- I want 6 wives! Sounds good to me!"

yet if there was someone on their street who was married to half a dozen attractive people, while they couldn't get a date you know they'd be complaining to everyone about how it's all that person's fault for stealing all their womens.
