"50 of your friends" -- please don't make assumptions if you weren't there. There seemed to be about 10 people who knew each other and the rest were people like me who said "I read about this or saw it, couldn't believe it, and don't want something this offensive to exist unchallenged in my neighborhood or city." And that was with less than 2 days notice, so I'm sure there are a lot more people who also recognize how offensive it is.
True, a 1 vs. 50 conversation is not a balanced conversation. But I disagree that someone super busy with opening a brand new business would have time to converse if they think it's just one crank with a crazy idea about their business name. Sometimes you do need public pressure to open the dialog. To her credit, she agreed to further future conversations about the name and theme/concept.
