I hate when Girls put the "All guys are careless scumbags" label on every guy.
The problem is that a high volume of Girls seem to be attracted to the Guys who might be attractive, yes - but don't have a care in the world for anything other than themselves. This applies to how they treat Girls, their Family, School, and anything else they don't find to be worthy of their attention, and will instead focus on what they want, which can vary on a spectrum that stretches from Video Games, to Partying with their Friends, and of course to mindless sex.
A lot of the times it may seem that Girls want to take Guys like these just to 'change' them - as if for sport. Well, go ahead and do it if you find it entertaining, just don't go complaining about how all Guys are terrible when you realize you've wasted a good chunk of time trying to change the traits and attitude of a person and it turns out they are not willing to change, as one would expect.
Going back to the 'Care' spectrum - Yes, I can agree that we men are animals. We find things we enjoy and we enjoy it as much as possible. Mindless Sex is always the big one that gets slapped on us, because emotion and passion are simply not needed for satisfaction in most men, most of the time Guys will have coitus (I'm watching Big Bang Theory while writing this!) with just about any girl, whether they've known them for 5 years or 5 hours. It is because of this, that most of the time Guys will look out for the Girls that look 'easy' as in 'easy to sleep with.' Guys who like mindless sex will take the girls that look the easiest, so they don't waste time not having sex and actually have sex. Typical criteria to look out for when finding 'easy' girls means incredibly high skirts, booty shorts, shirts showing excessive amounts of cleavage, etc. Of course, you girls look at your outfit and may go "I look so cute." To guys, it's a sign that you want it. Come on now, Girls - don't act stupid. You're the first ones to rant about how Guys are selfish animals and pigs, you know what we want, so why are you teasing? You're playing games, whether you know it or not - so Pro Tip: Dress classy if you want to find nice guys. Just some more food for thought. I'm not pointing any fingers, but take a look in the mirror and see if that is perhaps your problem.
Seriously. There's like, 6 Billion people in the world. If you come to these outrageous conclusions after complaining... You're sending the wrong signals to the wrong men.
Girls - I'm sure right now, whether you know it or not - there is a guy thinking about you. Not in the creepy stalker way, but in the "I would do anything and everything with you, I would love you like no other. I would rather do the most boring thing with you rather than doing what I think to be the most entertaining thing alone."
I know, because these are the thoughts going through my head as I listen to this girl I work with venting to me and a couple of others about her Boyfriend troubles of "Him not responding to my texts because he's with his friends." I immediately had a crush on this girl the day I met her, my second crush ever (the first one being in Middle School, so definitely the most serious feelings I've ever had). I refuse to be friend-zoned, and I continue to drop hints about my feelings for her, but she continues to put up with this Guy who could care less about her. I don't even get what she sees, he's a complete loser. We all work at Dunkin' Donuts, he's like 20 and doesn't go to school, this is like his full-time job, and she's working part time as she goes to school like me. He smells like fish and he mumbles to the point where he sentences are almost incoherent, and he's lazy. And it pains me to find another Girl who truly believes that all guys are scumbags, because the ones that are scumbags ruin it for us Good Guys.
Just some food for thought.
