If the science is bad, then the science is bad. If you do good science and find a result that doesn't fit your preconceived ideas of right and wrong, that doesn't make the science bad. You don't need to be concerned with the ethical impact of the truth, but you do need to be concerned with the ethics of your process.

I don't understand what the actions of pseudo-science bigots has to do with someone who is doing real science. Idiots will be idiots regardless of what real science says.
