yosemite: Thank you for your response. Once again, when it’s all spelled out, I find that we two agree more than we disagree. I understand how it can be irritating to you to have someone question your personal choices, especially when those choices aren’t hurting anyone else. I myself don’t have a problem with vegetarianism, for example, so those who label it irrational will not get any sympathy from me. You’re not going around telling other people that vegetarianism cured your cancer, though–that’s the sort of thing I would not stand by for.
Most skeptics are eager simply to put information into people’s hands so that they can make informed choices, and to stop people from spreading known falsehoods. Sorry if you consider that obnoxious, but I gather that you find a lot of my behaviour obnoxious. I’m not going to be polite and sit by while lies are pedaled to the uninformed.
You asked (again) how we decide what’s irrational or rational, but the answer to that question is in the last paragraph–the scientific method. If someone makes a claim that can be tested using science, but then refuses to submit the claim to testing, or if they see the negative results of the test and deny them, there is no reason to believe their claim, and it’s something of a personal goal for me to make more people were aware of that.
The scientific method helps me decide what’s rational and what’s irrational, not personal value judgements–that’s the way I try to keep myself rational, anyway. Maybe it doesn’t always work, but I would never say, “You shouldn’t believe that because I think it’s bunk.” I say, “You shouldn’t believe it because it’s been proven wrong,” or “because it is not supported empirically and there is no plausible physical mechanism,” or “because that has been demonstrated to be dangerous.”
Hopefully you wouldn’t consider me too obnoxious, because I don’t go around nagging people–I’ll bring it up once, and if they aren’t intersted in what I have to say, I’ll drop it. But I do wish that anytime a psychic or a fad diet promotor or a UFO enthusiast appeared on TV spouting ridiculous claims, a skeptic would be right there with them, explaining the more rational point of view. If that’s obnoxious, too bad. I find untruth and unreasoning credulity much more obnoxious.
