Oh come on, be honest.
We all objectify all day and as long as you do it in your head and know how to act and react normal, it's fine. Whatever anyone does in their head is fine as long as it stays there.
Anytime I hear someone say that they would never objectify anyone I feel this huge "let he who is without sin cast the first stone" kind of thing. We've all looked at someone else and thought "habbah habbah.
Just, again, keep it to yourself.
Some people like the girl without the tattoos on the left, others like the girl with the tattoos in the right. So? Just let her decide for herself and find someone else if you don't like it
