I just figure that the chair hogs don't read a site that dedicated and mannered cruisers maintain.
I read these message board nearly daily just to get the YOUR points of view on various topics. With our first cruise coming up, believe me, we will pick a lounge chair away from the pool (which is no big deal as far as I'm concerned) and sit in it! We will be properly dressed in the dining room, use our best manners (mine are pretty good, hubby lived alone too long :-), and will sit in available seats for the shows. However, if I were to see a child acting like a holy terror with no parental supervison or reprimands, I'm likely to use my "momma voice" to tell them to straighten up. Chalk that up to over 30 years of being the "momma" and I don't believe that there are vacations from manners for anyone at any age.
Just my 2 cents worth.
