Why do most atheists pursue spreading their "faith" with the same fervor as the evangelicals they hate?

HA. good question and so so apt! Obviously you are going to get some strong denials; I have no quarrel with Atheists per se but on this site they seem to be particularly venomous and go on the attack rather more often with with rather more violence than necessary to make their feelings known and honestly, I do find the same traits in them that they condemn in others who do not share their beliefs or lack thereof.
