Science has to answer for allowing the development of modern warfare, the atomic bomb or the machine gun are products of rational science. I too feel terrible about the HIV epidemic and I have previously stated that I am not religious and that certain branches of Christianity still need to change, but protestantism, quakerism and many other branches of Christianity do allow contraception. The horrific abuse of children is against the doctrine and rules of the church, those who have committed it and covered it up are running against their faith, you are confusing the true intentions and reasons of faith with people who commit atrocities in the name of faith.
No religion forbids scrubbing below the elbows and if it did a practitioner would not be allowed to perform medicine in the same way a rigorous Christian who refuses service to homosexuals is in breach of law.
You are stating extreme examples applying to minorities, the same can be said for scientific extremists. Eugenics, the Stalinist purges, chemical warfare, climate change, thalidomide sufferers and many other tragic situations have risen from rational scientific men who claim to have scientific rights and superiority.
From a rational, scientific purely empirical view you do have urges to fight and dominate and sexually reproduce as that is all we are here for, evolutionary development biology tells us this as a scientific fact. Compassion and ethics are rational flaws.
The religious have as much right to cry foul as you that is the point of multi-culturalism and democracy, to deny this is a gross hypocrisy against those you deem to be fascists. Religion and faith have a place and a worth in society, no-one has given a rational reason people shouldn't have a faith.
