Hey listen, I understand your dislike of the wave. It is silly and stupid and distracts from the game. But, it is Fun and fun is the main reason most "casual" fans go to the ballpark. Sometimes in life we just need to accept something is technically "wrong" but we just have to live with it.
I consider myself a baseball purist - the DH is stupid and the Wild Card is an abomination. I was also at Friday night's game and had a sick feeling in my stomach when the wave got rolling. But, let's put it in perspective - it is still August and we are only a Gardenhire-era late season collapse away from last place. Sometimes we just have to accept things, smile, and get along. And yes, I did participate in the wave on Friday, just like I did in the 1980s at the Dome when the wave was considered new and cool.
