"There are just as may outspoken atheists as there are Christians, they can be just as bad!!" is an argument I hear a lot, and it's a ridiculous one. You can't compare the two.
Outspoken Christians (and the religious in general) are telling you that unless you accept their personal savior and believe their specific story of supernatural - which mind you has no evidence and has to be taken on faith alone - you will be cast into eternal suffering because of a blight that you were born with. That is, (in the words of the late Christopher Hitchens) through no fault of your own, you're born sick and commanded to get better.
Outspoken atheists are saying that that's a completely ridiculous idea, not only laughable but harmful to human society, and that it's a sickening thing to be telling children.
