Mr. Calton may not have been appointed, but he did say something on the actual floor, and the other people voting the same way didn’t voice their disagreement. When somebody gives a stupid and/or offensive explanation for an action, and you’re doing the same action, you aren’t going to sit by and say nothing and let people believe that’s also your reason. This is even more true for politicians, whose entire lives are governed by image.
Imagine, for instance, you and I are together on a stage, asking people to vote against Obama (It’s a hypothetical, stay with me) and I was to shout out that people shouldn’t vote for a black person. Would you not immediately tell everyone that that was not your reason?
If it takes you a week to come up with an alternate reason, then you didn’t have one originally.
You’re right here of course. Her censure and banning from the chamber is naked suppression of dissent. Understandable, because these are pro-lifers, and to them this uppity Jewess pro-choice Democrat is deeply wrong, possibly evil.
