The niece of Martin Luther King Jr, Alveda King, has gone on a homophobic rant, saying it is ‘impossible’ for two men or women to marry.

King, an anti-gay activist, spoke at a panel discussion hosted by the adamantly homophobic Family Research Council.

In a video, published by Right Wing Watch, King, among other ramblings, said it is “impossible” for two people of the same sex to marry.

“It’s impossible to marry two men to each other or two women, it’s just not possible.

“The two cannot become one. It is biologically impossible, scientifically impossible, emotionally impossible, definitely spiritually impossible.

“You can actually hold a gun, Heaven forbid, and say, ‘do this marriage,’ now he or she may say, ‘okay,’ or they may say, ‘I won’t,’ but even if they speak the words, it is not possible, it is impossible. We have to be able to articulate that on all the levels we just said: spiritual, physical, science.”
