Bike riders are diverse in their characters just like other groups. You have the people who don't care what you ride or say, as long as you don't bash their family and the ones that think they and their machines are superior for some unknown reasons. Expect the people who think their's is best and your's sucks also to think that their poop doesn't stink. It's not as much about Harleys vs. Triumph as it is about people who feel strongly that it's their way or the highway. I'm a rider and think that if a person isn't a butthead or a dangerious idiot, they are more than welcome to hang with me. In every group (bikers included) there will be some buttheads and some idiots. It is just my preference to avoid those people as much as possible.
Two Harley riders (man & woman in HD dress) saw me in Target last night (carrying my helmet) and asked if that was my beautiful Triumph outside. I said yes, and thanked them. While walking away the man said "keep the rubber side down and ride safe". Those are my kind of people. A little friendly picking is cool, but since I live in a glass house, I'll never start throwing rocks.
