You can't really consider the peace of mind you get from it an advantage either; because then there's no reason to believe in any specific religion at all because all offer that same comfort in thinking you know what you don't.
I'm not a Christian, but I am a spiritual person after a certain sort. I most certainly can, and do, consider the peace of mind I get from it to be an advantage. Now YOU may do as you wish with regards to your opinion of whether or not peace of mind is an advantage. So, however, can I.
Accepting for a moment the idea that there is no god and what I can see, hear, taste, smell, and feel are the only things that exist (obviously untrue), then there's no reason whatsoever for me not to do whatever makes me feel genuinely happy and at peace.
Peace, of course, is something I cannot see, feel, taste, smell, or hear... but I still enjoy experiencing it. As an atheist, it is highly illogical for you to attempt to destroy someone's enjoyment of life. For it's been proven that those who are happy are better contributors to society.
And neither atheism nor religion seem to be precursors to being happy. Therefor, if one is happy as a religious person, then there's every reason to encourage them to continue to be happy.
Look, I just got done arguing with my crazy-ass cousin on Facebook, who is a non-cessationist Christian that seems to get some perverse pleasure out of informing the rest of us weíre doomed to be Chicken McNuggets in some lower-planar deep fryer just for asking too many questions or not believing in his version of god.
This, IMO, is why I find Christianity to be one of those religions that aren't a harmless practice. In fact, Christianity is psyhologically extremely damaging. Especially to young children who are raised in this belief system.
The Christian god is little more than a violent abuser... yet Christian children are raised to believe that this god is "loving." Therefor, the religion equates violent abuse with love. Murderous, wrathful, vengeful, violent, despotic... all ways of this god showing his 'love.'
So I agree with you in some part, that there ARE religions that are actively dangerous. In particular, religions such as this which show 'god' as a violent aggressor, while claiming that this being is "loving" and far above humans in both intelligence and capacity for love.
Not only that, but the Christian religion has brutalized and destroyed incredible numbers of peoples and cultures.

Iím not trying to convert you away from your beliefs or anything like thatÖIím just trying to give you a little dose of reality.
Unfortunately, the derisive tone you take with your "reality" bits, decries the first part of this statement.
So far as your Christian cousin is concerned, he's just trying to do the same for you. Clearly, you find it obnoxious as hell (and it is), so why do you do it to others? Was someone here trying to convert you?
[I'm being slightly devil's-advocate here... I assume that you're just venting, but I think it's still a valid question, given the tone you've since taken that you are supposedly educating the peasants herebouts as to the 'realities' of life]
