Yes. I don't like tattoos (though I love art in general). Don't like piercings either. Can't complain about lazy people (unless it severely impacts me), and I'm perfectly happy with religious people, as long as they don't try to push their views on me. I'm sure I have a bunch more of these things, my ex-girlfriend would probably be very happy to remind me of them.
I'm not about to restrict anybody to do anything. I certainly used to be much worse about this sort of thing (to the point where I didn't speak to my father for about a year until he stopped smoking (that was quite a few years ago now, I think I was ten or eleven)), but since college and since meeting a bunch of new friends with better outlooks on life, I've tried to simply live a drama-free life. One in which I create no hassle for myself or for others, which includes not openly criticising people for their choices like I used to.
However, I won't enter into a relationship with a smoker (even a little bit once a month), heavy drinker, and I'd think long and hard about someone with tattoos. Couldn't really tell you why. Not much of an issue these days either. Game development is such a woman-friendly career choice. ;)
Not sure if I answered your questions there, just typing as I think. :)
I've tried to figure out why this is with me, the closest I've come to it is that I think that humans are pretty good the way they are, no need to poison them or modify them.
I wear no jewelery of any kind, not even a watch and never will, same with you ?
The same is not true for smokers. Smoking <anything> is anti social.
It's useless trying to argue with addicts though. Just surprising there's so many drug users on HN. Sad.
But why do you have problems with that? It appears to me as if have problems with other people who don't fit into your personal view of how one should lead its life. Or is this the only thing?
I personally can completely understand that you don't see the added value for yourself, but I don't get the part where you have an irrational hatred of smoking. It seems like you want to restrict others the choice of leading their lives the way they see fit, without harming others.
Do you have this irrational hatred in other areas too? What do you think about lazy people, for example? Or people who have other religious views than yourself?
