Look. We all do dumb things at times. We all say stupid things at times. Most importantly, we all get things wrong at times. We have an opinion that is based on someone else's stupidity, or piss poor research on our own part, and we get called on it. Here's what you do, in case you didn't know/weren't taught.
You say, "I'm sorry, I didn't realize that a) those words hurt you, b) I had my facts wrong, c) I was misinformed, d) I did something wrong." Pick one option or all of them.
You don't say, "Well, a) you are stupid, get over it, b) it shouldn't hurt you because I know someone that said my words were funny/cool/acceptable, c) get your panties out of your butt and chill." Because that leads to a fight. And guess which is SHORTER, QUICKER, and BETTER? "I am sorry."
(And here's the thing: you can say you're sorry to make the OTHER PERSON feel better, and that's what you can be sorry about: hurting a fellow human. And that means we let you stay in our club of BEING human. And not an ambulatory asshole, shuffling around spouting crap and using up our oxygen.)
This is crap I taught my kids, why can't grownups learn it? "I'm sorry." Two words to make it all better.
And please go see my journalist friend Liz's journal where she is taking a poll on healthcare, both for US peeps and non. This is non-partisan. :)
If you'll excuse me, I'm off to do some yoga and find some zen. And I won't be turning on the news. OM.
