I fully agree that manners have generally gone out the window. And that some (women) are even insulted at the opening of a door or the rising from a table. For me the rising from seated is now just lifting my buttocks an inch or two. If the lady is aware of the custom, I get credit and if not, if she even notices she may think I'm just readjusting. The not doffing of one's hat when talking to someone maybe acceptable. What bothers me (and I am often a forgetful offender myself) is not removing sunglasses when conversing.

The example that Kid gave in his intial post of the elderly gentleman still engrained with Jim Crow laws just makes me shudder as well.
