Really? Is it unclear what's being asked there? I can't be skeptical about a social convention, and whether is the best way to do something?
Every time a westerner is portrayed on TV/Books/Movies or any kind of media, going to a country that uses a different kind of butt cleaning technique, it's always a huge joke. They always make fun of how dirty the other techniques are. But lots of countries look at us, wadding paper up to wipe our butts, and think we're the dirty ones.
I'm skeptical that our social convention is based on any kind of evidence, I'm skeptical that it really is the best way to cleanse despite our ethnocentric insistence and the societal pseudoscience behind that belief. So I was asking for objective studies to make a determination as to whether science indicated a best method, away from hype, woo, and cultural convention.
@sklivvz. Believe me, I know you're not hygiene experts. As far as I can tell, nobody here is really an expert on anything. I mean, are you an expert on microwaves, autism, the effects of salt in the human body, altering video footage, ghosts, AND climate change? You'd be quite the renaissance man if so, yet you answered questions on all of those. Since when is that an issue?
And speaking about off topic. Your question Will Humanity Self Destruct? Holy off topic. It's EITHER asking whether humanity will kill itself, which is completely subjective and with no data points. OR, more likely, it's asking about the Drake equation and, as you say, "Was Sagan biased by the times in which he lived? Is such a position tenable for a skeptic?" How does asking if something is a bias and tenable for a skeptic not violate the FAQ rule "it is not for philosophical discussions about skepticism itself."
You might not be an expert in health, but physician, heal thyself.
Unless there is some rule about it, I'm putting retarded high bounties on some of my questions and awarding them to like minded users, and then I'm deuces.
