"The worst side effect of casual sex is its cultural effect."
Mere speculation.
""Hookup culture" is extremely debased"
In your opinion, perhaps; I have no problem with it, and seems natural enough. Let people do what they will.
"and elevates deviant behavior to accepted status, if not a social requirement in some circles"
I would love to hear why you think sex is "deviant". It seems natural and healthy to me; after all, we were all born with the equipment built right in.
"being inexperienced, even for moral reasons, is looked down upon by many women in New York"
Being inexperienced in any important skill is good reason to be looked down upon. Your "moral reasons" are likely baseless. Why don't you try going and getting a job and see what they think of your inexperience, "even for moral reasons".
"However, if the sex is entirely private, and doesn't involve the woman I end up marrying, then I don't know about it, it's none of my business"
Even if you do know about it, it's still none of your business. Who do you think you are?
"What I don't like is living in a culture that engenders distrust and dislike between the sexes"
I have the feeling that the "distrust and dislike" you are evidently experiencing has nothing to do with culture and everything to do with women learning about your ridiculous beliefs. You've certainly attracted your fair share of "distrust and dislike" right here, and most of us aren't even women.
"and encourages dishonorable behavior in young people"
That's your opinion, and yours alone. I doubt you can back it up with anything other than "gut feeling".
"It seems like a lot of young American men behave unscrupulously and rack up a number not because they want to do so, but because of social pressures"
This is just laughable. I assure you, guys sleep with women because they want sex, not because of social pressure to "rack up numbers". And also, I love how you give a free pass to men (peer pressure!) but women are "immoral".
"they know most women won't respect them if they aren't at least as experienced as they are."
That's right. Women want to be treated right and they aren't interested in some hopeless n00b who doesn't know what to do. Like, say, you.
What a bunch of confused, regurgitated nonsense. You need to stop making foolish excuses and just go and get laid already.
