Probably not the best example to make your point. Would it have been impossible for the wake boat to stop, idle, then resume making wakes on the other side of the fisherman?
Now if there were skiers say out on a deep flat that I wanted to dropshot. So I motor right where they are, I'm invading their space at that point. If I sling a lure at them then I am definitely being a jerk. That's not what happened in your example though. They blew through an area they knew wasn't wide enough also breaking the law in the process. I'm not saying the anglers actions are justified but I'd be plenty mad myself.
I'm a big anti recreational guy. In my mind there are certain boats that don't belong on certain waters and I'm convinced most don't have much sense at all. Not that I don't think they have a right to use the lake too. It's just that most shouldn't even be allowed to tow a boat to the lake.
That said there are idiots on bass boats too. I had to give one an earful a couple weeks ago at Stockton. He apologized and I thanked him for that and went on.
Anyway I don't expect to make friends with that opinion but it is what it is.
