The way to fight religion is not through hate or division (eg fuck those Muslims, Christians, etc), but through education, and with morality taking its right place in replacing religion. Replacing mindless indoctrination with critical thought, common sense and literacy. There is really nothing good about religion, it shouldn't get a free pass, ever. The only positive side of religion is really the hijacking it does of morality. So, it's not that religion is good, it's the morality that makes it through in it, which religions then conveniently stir up and mix along with indoctrination, lies, contradictions, misconceptions, intolerance, fanaticism, confusion, etc to feed their enterprise of lies, and cash in on people's fear of death.
A lot of people (religious or not) tend to be caring and try to help others in many ways not because of religion, but because of a moral calling, which is part of basic human nature. That moral sense is what should be exalted, cultivated and taught, instead of religion. As religion gets replaced with a common sense of morality and civility the world could become a much less fucked up place.
One thing that gets rarely mentioned is what circumstances aid in prompting the flourish of religious radicalism. Governments in the west have some measure of blame in it, by doing things like imposing economic sanctions, or declaring proxy wars in middle east countries. That helps in creating the conditions for radicals to take the center stage and a bigger role over at those places. If the powers that be would
really want to fight off/suffocate religious radicalism they'd do so by opening up commerce, lifting absurd sanctions, bringing education and western values (back) over to those regions and also helping out to give people opportunities. It would be a long and difficult road ahead, but one good thing about the west is that it's constantly though slowly moving away from the tare of religion.
That's how you fight religion.
Unfortunately war is a business and making us hate muslims, and them us, is good business practice for some powerful folks. Just as it did in past centuries to divide people in between 'followers of god' and 'heretics'.
Not saying that those radical religious jerks who kill innocent victims in terrorist attacks aren't totally to blame for their depraved actions, of course, but people in high places who benefit from warmongering share the blame in aiding the conditions for it.
