Regardless, it's people not religion. There's radicals of everything. People sabotaging factories to promote "greenness" do not mean that helping the planet is a bad idea.
Religions were created to give explanations to things we couldn't explain at the time. Saying a creator did it was the only explanation we had at the time. We now have answers, solutions to those problems only beliefs could explain previously.
Religion is only good for morals nowadays. Teaching people to be kind, ETC, but we can do that without belief in a god. Or the bible.
