I hear you, man. I know you're not guilty of this, but fish stores generally do not do enough to discourage this myth (I'm mainly talking about Petco, etc here). Just by keeping so many in the store they help spread it. Then people see them sucking on the glass (of course there's never anything else in the tanks with the plecos) and they get the idea that they chow on algae all day. They're prominent in the store so people buy them and they're prominent in the store BECAUSE people buy them, but no one understands why they do. It's practically a given that you'll have a pleco in any tank among a certain set. Some barbs, etc, etc, and of course a pleco. Cichlids and blah blah, and, oh, a pleco. And then no one understands why they die. "Plecos don't really live that long - I've had four different ones in my community tank." FEED THEM OR STOP BUYING THEM.
