So this happened today.
“She… was much more ladylike (in 2006), but in the debate on Friday she came out swinging, and I think that’s because she feels threatened.” – Todd Akin re Claire McCaskill’s debate performance
It also happened last year.
“You have proven repeatedly that you are not a Lady, therefore, shall not be afforded due respect from me!” – Allen West re a speech made on the House floor by Debbie Wasserman Schultz, July 2011
And the year before that.
“I’ll treat you like a lady. Now act like one.” Arlen Specter, re Michelle Bachman interrupting him, January 2010
I’ve decided to stop looking.
Here’s an interesting exercise. Google “not a lady” and “not a gentleman” (with the quotes.) Take note of how many results, comparatively, are personal attacks.
