This certainly isn't a "Disney thing" - I just think people are more rude now in general. Class and manners are an "old fashion" kinda thing, now.
On another topic going on right now, I have just learned that I have been rude and demeaning to women, older persons, and parents (of either sex) holding children by offering them my seat on the bus.

The back on Big Thunder Mountain is amazing and Expedition Everest is totally different from the very back... you really feel it going over those hills!
(but of course, I didn't
