I'm for it - a lot of guys probably couldn't be bothered to clean under the foreskin, and many parents are too stupid or embarrassed to teach them how to do it when the kid is young. And I can't remember any man who ever said they remember the pain of their circumcision when they were babies - it's painful, but no one remembers things from infancy. Some boys may never develop a foreskin that retracts properly, and therefore they may be unable to clean it properly. If the parents care enough to address the problem, this will mean embarrassing visits to the doctor so the boy can get his genitals poked and prodded...grown men may not be so embarrassed about this, but a pre-teen or a teenage boy would probably be. Sometimes the foreskin may cause problems that end in circumcision being required when the boy is older, and as someone brought up already, it's definitely no picnic getting circumcised when you're beyond infancy.
Also, if the uncut boy sees that most men (including any male friends) have a cleanly circumcized penis and he's got the weird one, don't you think that's going to make him feel like the odd man out? As has already been pointed out, a member's child already felt that way and attempted a DIY circumcision because he felt like a freak.
And, men who have been circumcised have a much lower chance of contracting HIV than those who are uncut.
The arguments against circumcision are kind of...well...lacking in sense. I know people will whine "But it looks more naturrrrrrallll" - not when most of the male population is already circumcised. Strike one. Others will whine, "It looks more aesthetically pleasing" - that's in the eye of the beholder, and I have found that a lot of women and men find a circumcised penis to look better because that's what everyone is used to seeing. Strike two. They say circumcision is painful - you know what else is painful? Trying to pull back a faulty foreskin, or having a UTI that may have never come about had there been no foreskin. Strike three.

I also think that stuff about how circumcision greatly reduces the sensitivity of the penis is just a bunch of crap used to scare people into not getting their male babies cut. I've known quite a few circumcised men who required very little stimulation to achieve orgasm. Besides, how would they know what kind of sensation they may or may not be missing out on if they're circumcised as babies?
