I've introduced everyone I've been involved with to the band, older and younger alike. Most have absorbed my musical preferences after we've broken up. None became massive NO fans that I'm aware of. I like the thrill of dating a non fan, because I get to share really fantastic music with them for a first time - break their NO virginity as it were.
I only knew one person who was vehemently against the band, and that's only because they were jealous that they couldn't play like *insert band member here*.
