People are comparing Ken's actions to Chima from BB and Sandro and asking why Ken was not immediately ejected, as they were. I think that there is one major difference: both Chima and Sandro deliberately damaged equipment. Chima threw her microphone into the water and Sandro kicked things aside as he left and then struck down a camera. Those actions demanded expulsion on the spot.
Ken certainly has some huge anger issues to work through. Remember how he glared at Heidi a few weeks ago during her critique? She actually called him out on it. And as for getting his own room...OMG! He needed to go and I'm happy to be rid of him and his attitude, but his actions were verbal only and I think there in lies the difference.
