Hm, I read an editorial about abortion the other day. It was pretty good, except for that it was a total attack on others, so anyone who might disagree with them would normally just shut them off at the first few sentences.
It was against my beliefs, but whatever. I read it, and it was pretty sick, but for its intended audience, it'd be good. My stance on abortion: I don't think I could ever abort my unborn child... But, given that I'm not everyone's mother, fuck it. Let them do what they want. Babies die all the time, it sucks, but until it happens to me, through abortion I didn't consent to, I don't care.
As for alcohol: More or less the same thing. If you want to get drunk and stupid, do it in a bar or where you can't screw someone else's life up. Aside from that, go for it. Get alcohol poisoning for all I care - it's just one less person to have to deal with.
Though, practiacally speaking, that's not going to happen. People will still drink in public and ruin other's lives, although, I believe it to be far worse to try and prohibit, and I use that word for a reason, alcohol, not only because people will revolt, but because your taking away people's freedoms and probably rights. :p
