Unfortunately, repeating an ill meme, particularly in a way that seems as if you are falling into the trap isn't particularly ironic or clever, it's just socially awkward.

I understand what you're going for, but it doesn't accomplish your goal, and it just continues a stereotype rather than working to create an environment that's conducive for discussion.

I understand that, and I normally am not the kind of person to say such things, but I thought it was rather meta-ironic, considering the xkcd comic...

edit: unless, of course, you were trying to be meta-ironic too...

The problem is, these ironies and meta-ironies are just as old, trite, tiring, and grating as the same thing meant seriously. Believe me, meta-irony on this topic has been done before, many times, and not only based on the irony of an xkcd comic.

It might be the first time you do this, and you think it's funny, clever, and 'meta-ironic' (oooh). I suppose it's somewhat like lists of jokes that people forward around: funny the first few times, and "I'm going to auto-killfile this" after a few years of hearing the same ones.
