I don't ignore them utterly, but I don't put much weight on them. I can't relate to "jealousy is bad," so I let them have their opinion, but don't really get into that conversation. I know enough smart, happy people who feel that jealousy's just fine, but how it's managed/used really matters, that I know that the "jealousy is bad" people aren't necessarily dominant. Maybe they're just more vocal.

If most people who don't like cilantro spoke up about it, and most who do like cilantro were relatively quiet about it, one would think most people don't like cilantro.
