Frankly I find your overly emotional response to my opinion about tubes to be evidence to the contrary. My opinion on tubes wasn't aimed at you or anyone else specifically. I do think your response belies you're claims of being a scientist, but whatever. Where's your objectivity? You called me angry and yet, the only ire I see here is yours, aimed at me. I don't need it either.
