That fact that you linked atheism, homosexuality and racism says a lot about the way you think. Is there a pill that can prevent me from ever thinking like that (if you can call it thinking)?
The racism one should be given. However there is nothing to treat with atheism and homosexuality. One is a personal belief that you should not interfere with so long as they keep their beliefs to themselves. The other is a life style that is none of your business that you also should not interfere with.
Well first of all religious believers and scientist are always in conflict with each other. So if People esp. (religious believers) want scientist to make some pill to treat atheist, homosexuality, and racism, that would just be against your religious beliefs and a contradictory statement. Accept people for the way they are and not force biblical doctrine on others for your selfish reasons. Then acting like a saint cause you put your faith in god, so that means you are automatically better than others. Oh Please. XD
Atheism and homosexuality are not disorders. As for racism, I don't know that you can create a pill that would change ones opinion about people who are different.
