Sometimes I like to be a dick to people that piss me off, and self-righteous d-bags on some bull **** moral crusade piss me off quite a bit.
If someone doesn't like the term, or is uncomfortable saying it, or doesn't want to for whatever reason, that's fine with me. To each his own.
But to go the extra mile to actively announce in passing that they're refraining is a different story and worthy of ridicule.
When was the last time anyone referred to "The Buffalo football team" or "The Dallas football team"? Never. If not referring to team name it's just Buffalo or Dallas. Same with Washington - unless, of course, you're trying to communicate something else.
It's more annoying and worthy of ridicule because it's irrelevant to the point being discussed. It would be like if you were discussing the architecture of the WH and some dickhead kept calling it the Emperor's house to make sure everyone knows he thinks Obama fancies himself Emperor. If you were discussing politics it would be one thing, but when you slide your politics into a completely unrelated discussion it's another.
