While IQ tests can be a bit flawed... I'd be ok with there being a range of intelligence/common-sense tests before people were allowed to procreate.  The amount of borderline retarded fat monstrosities I see around with 6, 7, 8+ children all living off welfare is getting out of hand.  Why should my taxes pay for that?  Why should the society in which I live have to be demonstrably worse than it could be because half the money is going to support these giant socially-perpetuating families? Evolution has stopped due to shit like this.
