Atheist Revolution argues we do but that it’s not our fault because religion started it and there is no avoiding it as long as religion perpetuates it, so we cannot be blamed for just acknowledging it’s there:
I think that an “us vs. them” mentality was established long ago by religious believers and has been kept alive today primarily by religious believers. To say that outspoken atheists are somehow guilty of causing it or even maintaining it denies this basic reality: it exists and will continue to exist whether we express ourselves or not.
I understand how it might seem to make sense to accuse outspoken atheists of fanning the flames of conflict. But is that really what we are doing? Isn’t it a bit more accurate to say that we are acknowledging what already is the case and exercising our right to contribute to the discussion?
