Why the hell can't guys respect exotic dancers!?

First off I've been dancing approximately for 9 months part-time. I go to college full-time as a dental hygienist. I am a 20 year old normal respectable good-looking girl from a middle cl family, my parents are the nicest people ever (they are completely unaware I do this). I've never been molested,d and I'm certainly not promiscuous. I don't tamper with drugs nor do I have a leech boyfriend or any kids. I dance because I cannot go to school full-time and work a crappy tiring 40 hour week job at the same time. Its too overwhelming for me, and I also got myself into a little credit card mess. Anyways my question is why do guys have such little respect for us? Why is it that they can come in and spend their hard earned paychecks on us but they can't respect us? I just don't get what posses a guy to think that its o.k. to stick their fingers in places were they don't belong. Do the guys that pull this sh*t were they not brought up with women in their lives? It just saddens me that there are men out there that think so little of women
