I guess that's what Lindsay does, really. He doesn't only meme and smirk. I wonder, though - since they aren't actually *interested* in arguing, just in issuing polemics, if engaging with any level of intellectually sincerity gives them more validity than they deserve (and by "they" I mean anyone who puts forward these arguments, whether it's operators or useful idiots. I observe that there are some people who will engage with sincerity.)
