You're assuming it is the job of every person in the world to carry out the continuation of humanity. It's NOT. Some people don't want to have babies, some people can't have babies. They shouldn't be punished for this. Telling someone they have to be with a partner of the opposite sex so they can have kids isn't far off from eugenics. You are FORCING people to do something they don't want to do. I can't really see you carrying out a crusade against single people, so just leave gays alone, yeah? Also, adoption. I'm going to assume you have a problem with that, but honestly, it helps.
just adding my veiw...this isn't to izzy, but to some other people...so it's ok for someone to adopt or never be married/have kids, or that if someone can't have kids, it's ok, but if someone choose not to have kids because their partner is the same gender, it's suddenly all wrong?
