You are right! How many "gay", "fat" babies are going to make it out of the womb?
It will be interesting to see the division on the right on this issue, as well.
Here's something I found out in the process of looking for this article that really, really pisses me off. Doctors setting themselves up as the decisionmakers--because of political pressure--have NOT told some people whose children are at high risk about a test that would let them know if their kid will be born deaf or with a specific form or mental retardation. This seems to me something parents will want to know, and the test is something these folks deserve to know about. Yet deaf-nuts and Downs-nuts have pressured doctors away from even MENTIONING the tests, nominally out of their perception that 'it's okay to be deaf' and 'it's okay to have Down's,' but in reality, out of fear parents will selectively abort the deaf or retarded kids who are these nut groups' future. You can bet gays would try the same kind of thing if the gene is discovered.
