I think saying a person is selfish b/c of blah blah blah is one of the meanest things I have ever heard.
What about people that want to have children but can't. It isn't their choice to be 'selfish'. If you know a person that suffers from infertility you wouldn't say that. Then you have people who don't give a rat's ass about their kids keep reproducing like bunnies b/c they get taken away and they want a kid to keep. We had a young couple a few years ago that came from a neighoring county, said they were from out of state, gave fake names, etc, b/c their other 2-3 kids had been taken away and they wanted to keep this one.
