Finding something absurd is a GREAT reason to talk about it in fact. If people thought things were absurd and never spoke about it, no one else could prove them wrong or learn that it is absurd themselves.
As for God doing meaningless things, you can't use the "we are pots and he is the potter so who are we to question what he does" argument, because that also means who are we to say we can't question it? And also that argument is like what MuraRengan (sp?) did in his blog post about saying God must be illogical and make no sense in order to have made the Universe. You're just saying something you don't get and playing it off as an answer. It isn't even understandable as to why we couldn't comprehend a reason, surely after it is all said and done God could be like, "Oh, this is why we did this nonsense..." and then we could be like, "Oh okay!" All things have sufficient reason, and if a sufficient reason cannot be surmised, then it isn't any reason, which just doesn't happen in reality. It is absurd.
