Without realizing it, you are probably showing more disdain for religion by feeling/speaking this way, than do the people who debate against it.
an expression of disdain is a suggestion of what i'd feel in regards to a subject, so not feeling of anything for something doesn't actually express more disdain.
what i am guessing you mean to say is that it is in someway more disrespectful to religions, because rather then viewing them particularly negatively or positively, it shows that i'm not taking them seriously in the first place.
i've had this debate in the past when i considered making online games out of religions
Short answer yes. I would change the wording to "displace". As one of The Four Horsemen put it: When religion takes on the relevance of other outdated bronze age era belief systems, like astrology, humanity will benefit.

"The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents... Some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new Dark Age. " - H.P. Lovecraft
