And Skip Stam thinks it's just fine:
The Bible Baptist handbook states: “The school reserves the right, within its sole discretion, to refuse admission of an applicant or to discontinue enrollment of a current student. This includes, but is not limited to, living in, condoning or supporting any form of sexual immorality (or) practicing or promoting a homosexual lifestyle or alternative gender identity.”
N.C. Rep. Paul Stam, a Republican from Apex who sponsored the voucher program in the state legislature, said the program does not discriminate. “Parents choose where to send children. And parents are free to choose whatever school they want within the hundreds of possibilities,” he said.
While it's very likely Stam does understand the program allows for discrimination, he chooses to pursue the fallacy argumentum ad temperantiam (argument to moderation), in which the statistics are brought into play: More schools don't discriminate than those who do, so it's not a problem. The truth is somewhere in-between. It's actually a clever position (if we allow him to maintain it), because discrimination would have to rise to 50+% for him to admit there's a problem. Needless to say, we can't see the ass-end of him soon enough.
