A) There's a huge gap between what you are describing and wearing a low cut shirt.
B) No, I shouldn't have a problem with you looking, but it shouldn't give you the right to stare, drool, or violate my personal space.
The situation in question started because the guy was giving "advice" on how to check out women. He was describing his body language and position, and people were like "Uh, that pretty much makes you look like you're checking out her boobs." His response: "I do look at her boobs and when she notices me looking I just smile. If she didn't want me to look she wouldn't be wearing that." Somebody else separately made a comment about people wearing "suggestive clothing" and another person was like "Don't assume anything about people's clothing except they like what they are wearing." So I +1d and said "Yeah some of these comments are kinda creepy." The second guy kinda backed off, but the first guy chimed back in and that was when he stated "Low cut tops are an invitation to look."
After I said HELL NO THEY ARE NOT he said "Well I'm going to look anyway no matter if she wants it or not."
Skeezebucket.
And like I said, made even worse by the fact that this guy was in another thread going on and on about how he's a VERY STRONG CHRISTIAN and he's LIVING HIS LIFE BY THE COMMANDS OF GOD. He got on me about not currently attending a church because GOD COMMANDS WE GO TO CHURCH AND PRAISE WITH OTHER CHRISTIANS.
I'm pretty sure God doesn't want you being a lecherous douche either bro.
Obviously men have a penis and they're going to look. But you can look, just don't gawk. And if you get CAUGHT looking don't be proud of yourself and pat yourself on the back because that means you weren't "just looking." That puts you in the "gawking" circle.
Just. Gross.
Then they shouldn't get mad when people stare, or ... Post they pic on POW or Facebook. There is a fine line btw "wearing whatever he **** you want" & decency.
You know what's decent? Treating other people with respect. Not gawking or putting them up on a public website for mockery.
