As far as the thread about posting stuff and "making our letters look bad" it wasn't started as an affirmation, it was started as a discussion. If we all jumped on and said "yes! correct! we should never mention anything but philanthropy in our posts!" that would be too PC. I didn't see that though. (thank God)
As to the Reagan article, I agree that whether the poster agreed or disagreed with it, it was poor taste to post it. I'm starting to think Nixon almost got off easier when he died, but I digress. My main point is that on the several MBs I visit online, NONE of them are capable of having a flame-free political discussion. If you decide to wade into those waters with people you don't really know and without benefit of face to face contact - all I can say is be sure you are wearing your hip boots.
