I think medical treatments should be tested on humans.... all those in prison serving time for sex offences, especially the paedos.... why test on dogs and rats, when the results will be far more applicable when tested on some kiddie fiddler.... lets be honest, who cares if they end up dying or suffering from bad side effects....
The problem is that only a few select can have this gene therapy. Namely the rich and important. Everyone else won't. This is would become another version of the movie "Gattaca". Everyone else would be screwed. The gene boosted people would get the best education, jobs and social standing. The ones without would be labeled as "useless" except for low-end jobs.
I say absolutely not. Watch Gattaca. It holds all the answers.
Lets suppose that the gay gene for example was a factor. But, evidence tells us that the gay gene isn't a single gene. It is, rather, a symphony of genes acting in unison. Say that the gay genes can be pin pointed and eradicated; there is nothing to say that other genes won't fire at key moments and that homosexuality won't continue to be a "problem".
Gene therapy is a huge step forward for human kind. I say test away. Besides, there are plenty of ignorant humans to choose from, when selecting a subject for the experiments.
Right?
