I came across this article about genetically selecting 'superior' offspring. If a 'gay gene' was identified and used as a basis to terminate a fetus, would people do it? Some religious fundamentalists would be huge proponents of this, depsite their rejection of abortions as an acceptable practice.

One could say that their narrow minds are a disease, as they say we are. Anyways, here's an article you should read on the topic.
