How many people have had any change in attitude or thought by a slogan on a T-shirt? Seems like a rather ridiculous battle. Why not devote time, instead, to a worthwhile pursuit instead of getting branded as a troublemaker?

That's not the point. Other students are permitted to wear t-shirts with messages. She isn't. This has already been decided in the courts.

I think any advertising promotes an issue. Perhaps a mind isn't changed, but it causes dialog. Then again, maybe a mind is changed. If advertising didn't work...why advertise. That's all the T-shirt slogan is...advertisement.
My brother once saw a guy in Austin wearing a T-shirt promoting a 10K run for "March of Dimes". Although he was just in town on business for a few days he signed up for the run.
