Power boaters often have a strange compulsion to tell sailors that they don't understand or like sailboats. You don't have to ask their opinion. They're just compelled to let you know they don't approve. Jerks. How do you educate a power boater. Ya can't.
Ditto for people that don't like cats. Absolute compulsion to let you know they don't like them. Take a look at Minnewaska's posts on this thread. Nothing constructive to offer to the original poster, and a hijacking of the thread. If Minne-whatever can explain his compulsion to be a jerk, then maybe it will lead to an understanding of power boaters. Not that there'd be any point to it, though.
