The more you take value judgments out of the equation about what others enjoy or what you perceive yourself to be to others, the easier life will be in general and enjoying a pipe.
No idea how someone is "showing off" because a pipe has a blast of some kind, really doesn't make sense, but for some reason it affects you that way. Maybe do some research into the history/manufacture/look of pipes and some context may ease that angst or concern. If you don't like anything but smooth, it's your preference but I've never perceived anyone making some kind of statement by using a pipe that isn't smooth.
Off to enjoy a Pete with a lovely blast - maybe the dogs have been taunting me all this time - "Showooof!"
