"Birfers"

For the record, I think the "birthers" out there are crazy bunch. End of that.

But something about referring to them as "birfers" kept bugging me.

Then I realized what it was.

Using the f sound in place of the soft th sound in spoken English is characteristic of African-American Vernacular English (AAVE).

Are people using the "birfer" term mocking African-Americans?

Are they subconsciously racist?

I anticipate back-bending and apologies are forthcoming.
