From a reader:

Regarding free speech in school, a child wearing a T-shirt that says “Al Gore is right–Global Warming is killing polar bears” will not be disciplined because principals will find nothing objectionable in it, whereas a child wearing a T-shirt that says “Abortion is murder” will be invited to disrobe. But in fact, the first T-shirt is just as politically tendentious. That is why content-neutrality is so important.
Regarding Bloomberg, we get it, you don’t like him; but can you please spare a thought for the non-aligned voter, the Perotista? Where do we go? Whom do we vote for? Brownback? Romney? Neither of those will do; but Hillary is also out of the question.
I’m always stunned by the hate e-mails you publish but it’s good to see them occasionally, as a reminder of what’s out there. Speaking for myself, I always enjoy your writing and feel great respect for your work!

Me: 1) Good point. 2) I don’t know, but life is unfair. 3) Thanks!
