This is so true. The guy who sits next to me at work told me he told his son, I don't care if you are gay you are having kids until you have a boy to carry on the family name. And they say we are selfish??
I would be willing to bet that the guy who said that was adopted and has no 'real' family link, so he WILL make sure that he passes on SOMETHING of him to future generations (even if it is ignorance). I wouldn't be surprised if he had not had a boy, he would have had 10 girls until he had a boy for his namesake.
Sad, beyond words.
