Since someone brought up Marx and his oh-so-famous opiate quote, I'll quote the whole hog from his contribution to the Critique of Hegel's Philosophy of Right. It's a really beautiful piece of literature, even in its translated form:
Religious distress is at the same time the expression of real distress and the protest against real distress. Religion is the sigh of the oppressed creature, the heart of a heartless world, just as it is the spirit of a spiritless situation. It is the opium of the people.
The abolition of religion as the illusory happiness of the people is required for their real happiness. The demand to give up the illusions about its condition is the demand to give up a condition which needs illusions. The criticism of religion is therefore in embryo the criticism of the vale of woe, the halo of which is religion.
Criticism has plucked the imaginary flowers from the chain not so that man will wear the chain without any fantasy or consolation, but so that he will shake off the chain and cull the living flower.
The underlined sentence is rather poignant, and the very last sentence of the third paragraph is truly masterful. You can even subsitute 'kiss' for 'cull' if culling doesn't floats your boat.
In any case, religion is a belief, and like all belief, open to criticism, satire and ridicule. You may defend religion from criticism (i.e. bashing), but you may not request the detractors of religion to cease their criticism. Or are you afraid that reason will eviscerate religion, and extirpate it like the disease it is?
Edit: I invite anyone and everyone to PM me and the other 'infidels' with any 'logical' arguments for the existence of God. Perhaps you'll like to try your hand at the Cosmological Argument? Or the Teleological Argument? Or perhaps the puerile Ontological Argument? We'll be overjoyed at the chance to beat sense into you, one annihilated piece of apologetics at a time.
