Personally I think abortions should be illegal except in cases of genetic defect, including the genetic defect of having the gay gene.
There is no singular gay gene. It's a combination of several defects, none of which all have to exist simultaneously. That's why there are all different types of gay people. It's analogous to the common cold in its complexity.
Also, you sound like a Ruth Bader Ginsburg/Margret Sanger eugenicist. Super Race Aryans of Nazi Germany would be proud of you.
I also think poor people should be sterilized so they can't bear more poor people.
You first. I'll donate a set of bolt cutters!
Or would a mini-scalpel be more appropriate...
