Do you agree with Biden that you "ain't black" if you're considering voting for Trump?

Biden recently implied in a contentious interview with Charlamagne tha God, a black radio host, that black people considering voting for Trump are not black (essentially employing the No True Scotsman fallacy). From an article about the exchange:

’“If you have a problem figuring out if you’re for me or Trump, then you ain’t black,” Biden said.

“It don’t have nothing to do with Trump — it has to do with the fact that I want something for my community,” Charlamagne countered. Biden replied that he should take a look at his voting record to see his longtime support for the black community.’

Biden’s adviser Symone Sanders claimed the comments were made in “jest”. That defense never seems to work well for Trump; will it work for Biden?
