It goes both ways and the respect should be shown on both sides.
If a dude comes at a girl in a raunchy rude or disrespectful manner then he deserves to be aired out.
If he comes at her correct and shes not interested, she got every right to not be interested, but try and shut him down in a respectful manner, no harm no hard feelings on either side.
I get why females have their guard up and are quick to reply in a harsh manner, even to guys with good intent, especially hot women who get approached regularly throughout the day.
At the same time though, you got famous people and celebs, who get stopped regularly and can take the time to respond to people in a decent manner, even when I'm sure it gets irritating after a while. All I'm saying is seperate good intent from thirst bags.
when I bagged some girl this summer who tried to make me look like a fool after my, "hi how are you" didn't work. I told her straight up, I can take rejection and wouldve got the point off a simple, I'm not interested. She kinda got emotional talking about how she was sorry but how it gets irritating the way some dudes approach her. We started chopping it up a bit, and later that evening we were getting drinks.
