Apparently, it is having an impact over in England. For example, Christian couples have been denied the right to adopt on grounds that the children might be brainwashed. Here.
Being told you can't adopt a child because of what you believe about religions strikes me as an extreme form of anti-religious discrimination. Jim Crow returns in the name of reason and science.
One would have to wonder what would happen if Richard Dawkins had a son or daughter who, say, decided to be received into the Catholic Church. Would he say "Well, we taught you to think for yourself, and this is what you have decided. I don't agree personally, but far be it from me to brainwash you and make your decision for you."
A lot of Christians on this site respond differently to New Atheists than they do to other atheists, I think there is a reason for this. New Atheism is socially divisive in a way that Old Atheism is not. Even in discussions with some passionate atheists, I always had the feeling that there was a common purpose underlying the exchange, a desire to understand our differences better. I think that common purpose is lost with New Atheism.
Even strongly atheistic philosophy professors would tell me that the presence of Christians like Plantinga, Swinburne, and Robert and Marilyn Adams were good for philosophy.
I think that New Atheists have contributed nothing of substance to argumentation for and against the existence of God. So, in one sense, a successful critique of New Atheist arguments shouldn't be confused with a successful critique of atheist arguments in general. But New Atheism has to be recognized for what it is as a social phenomenon, and I find very harmful.
