James: I can tell you that at least 3, probably 4, of those myths are truthful. CO2 *does* influence climate(just look at its infrared absorption spectrum, it’s pretty blatant), the evidence for CFCs causing ozone depletion seems fairly legit, HIV destroying the immune system and causing AIDS is rock-solid, and public schools do teach kids things they need to know. For that matter, you’re probably wrong about saturated fat, but I don’t know enough to be sure of that. Mind you, in all but the case of HIV the point you’re making is fairly legitimate – AGW and ozone are overblown, and the public education system has a whole mess of problems – but the statements you made are not mythical.
