i wonder if these same two females would wear t shirts to a nice restaurant, or a cocktail party? you would think they would have enough sense to realize that the SOTU is not the place for clothes most people wear when cleaning the barn!
I grew up giving not one whit for fashion or fitting in. It's just clothing, and taking an elitist attitude about outward attire really doesn't help any conservative cause. It's as bad as raising your eyebrows because your neighbor or coworker buys their 'nice' clothes from Walmart or Target instead of Nieman Marcus. Who really cares, as long as they can do the work?
It would be totally different if she had been refused entrance and told to go find something else to wear. Occasionally people do unorthodox things to make a valid point. It's not as if she committed some great 'sin' or had a 'moral lapse' like they brush under the rug in the Demoncrat party.
In the context of Sheehan being ejected though, it makes sense. It's not the Tshirt, it's the slogan. I agree with freeper Robert A. Cook, PE, it castrates Sheehan.
