Thank you, although I still do not see what my age has to do with anything, and yes I am already very deeply involved in politics, and no this is certainly not the greatest of my worries, not anywhere in the top 50%.
However, I take issue with your house analogy. I think of it more as walking into a Wal-Mart and telling people to tone down the raucousness. Sure, it's privately owned, but it is a very public place, where anyone can waltz in off the street and start talking - or shopping, or whatever. I think that's a significant difference, and I'm glad you could be civil AND disagree.
Age has nothing to do with it. You brought it up. Civility has no age limits.
