You have made an interesting point but I think your arguments would have more force if you exercised some restraint in categorically stating your opinions about what is wrong and in what way as facts, basically.

Anyway, while I agree on these other types of "wrong" being important, I don't know about calling 1-3. wrong, per se. Also, I'm curious what part of linguistics you consider to belong under the "vanity" label, and why it would be apt to call "pointless" facts (like the age of the Earth) wrong.
