Hm, interesting. I'll definitely think about it (which is probably more productive than me being put off or just ignoring it anyway). My first guess is that it has something to do with sarcasm and/or ridicule. Ridicule usually condemns--and puts out of the sphere of argument--a point far better than arguing against it and therefore respecting and taking it seriously as an argument. Maybe sometimes ridicule is warranted, but I think one should be careful. And it's the not even taking it seriously as an argument part that seems, I guess, "I am up here, and you are down here." That's my initial impression about why I respond that way, at least.
