School is supposed to be where young Americans learn about the Constitution's guarantee of freedom of speech.
It's not where students should be ridiculed for expressing a preference in the presidential election. Children can't vote, but they can let the adults who do know which candidate they like and why.
That could create one of those coveted teachable moments in which students, guided by a capable teacher, get to exchange ideas and learn something valuable without resorting to a dull textbook, website entry, or video.
Unfortunately, that's not what happened to Samantha Pawlucy, a 16-year-old sophomore at Charles Carroll High School, who was ridiculed by her geometry teacher on Sept. 28 for wearing a pink T-shirt expressing support for the Romney-Ryan presidential election ticket.
