If a person wants to fall for the other’s looks, it will happen. That is for certain, it is the way we are wired.
“And so if for whatever reason, I want a book WITH a cover, I am free to judge ?…..Are the girls here trying to claim they don’t say no to boys regularly because of looks ?! (Or do i only know weird girls?)”
You are always within your right to do whatever you choose. If it is approval of your opinions you seek, I happen to disagree. But apparently you are being set up with girls of the same mindset so it apparently works for both sides of the mechitza just as much as it fails. In that case, this dispute is simply a matter of personal preference and therefore a waste.
