And here we go again, trying to be indirectly direct.

There is no hole to fill through the activity. Ever sat down an enjoyed a game of people-watching? Undoubtedly, you have.

Labeling ANYTHING as "bad" or "unhealthy" is a personal opinion and you know very well that you have the same views on other things in life.

Who says the negativity is constant? Negative things are just the most glaring and easy to point a finger at.

Yes, my own "sexual practices" are more healthy than another's FOR ME. F.O.R. M.E.. Being FOR ME, I shall judge it accordingly. Living the way of others, sexually, would kill me as I'ma clingy personality and, from experience, cannot get used to any sort of repeated rejection or let-down and I NEED commitment and loyalty. Ohnoes, I pointed out a self flaw, how dare I judge myself!? And yes, such a trait is a negative in most relationships. However, some are attracted to the clingy ones. Always keep, in the back of your head, to each his own. No matter how hard I judge someone, it's back there. Doesn't mean I have to come out and say it each time, as some protective, sugar-coated padding.

Condescending, somewhat. If you aren't EVER, then you may as well go unnoticed. Watching people so often you learn that EVERYONE is a bit of a hypocrit. When you watch people, you tend to listen too. Over time, you will see them fumble into hypocracy quite often. Humans are hypocrits, end of story. Should I ever feel the PERSONAL need to change myself, yes. No need to change for others.

Edit:
"But maybe to someone finding love IS life."
And, believe it or not, this is where I fall. And yes, it has negatively effected my life. I neglected much in my Junior and Senior years of high school, focused on it.
