Actually, you are missing a world of fun. There is not a better sport in the world, in my opinion.
I once played college football, raced motocross and hare scrambles.., but can't do those anymore. Yet, at 72 years old, I just missed winning the Wave North Americans. Only sport I know where you can be competitive as long as someone can load you on the boat and stick a tiller in your hand.

And, how about knowledge? You have to have a grasp of aerodynamics, aquadynamics, have to be physically able to trim sails to optimum speed, know angles of attack, know the rules of the road, understand all about weather (i.e., sea breezes effects, frontal winds, puffs, shore effects, etc.) and then put them all together in a game of chess on the water.

Sorry, but reaching back and forth dodging PWC is not my cup of tea.

Racing sailboats IS where it is at. What you are seeing in these Forums are folks that are simply wanting to do it the way that is the most fun for them. It takes organization to have regattas. It DOES NOT take organization to reach around a lake.
So, that organization part is what you are witnessing here. There is NO ONE hostile here. We are all working toward a common goal -- having fun and fair racing.
