Democrat Party

Why do we let it pass when we are called the Democrat Party? We know they are demeaning us when they use it. I hear it in television interviews and democrats just let it pass. How hard would it be to correct it?

To be civil, we could pretend it was an honest mistake. Just a quick correction like you would if they had called you by the wrong name. If the situation called for it, we could even slip in a half-hidden patronizing or condescending tone.

It is so offensive. And it's aggressively rude. And we just take it. Why?
