He stands at the intersection just before Ring Road, which runs about the campus. Every day he has a different sign, and a different thing to shout. Mostly it's about who and what will not enter the Kingdom of Heaven, which so far includes scientists, the United Nations, environmentalists, lesbians, sodomites, and chemicals.
Clearly his logic circuits aren't connected in the usual ways and there's no point attempting to engage him in discussion, or even ask him what his aims are--does he really think he'll change anyone's mind or heart by shouting at them that they're damned? He shouted at me two days ago about women who hated men but copied them by cutting their hair short, and I was tempted to whip my braid out from under my rainjacket, but then he probably would have gone on to my wearing men's clothing or something (rainjacket is made from chemicals?).
But I remembered the advice I'd been given for walking the picket line (these many years ago) of responding to hostility or abuse by saying "Have a nice day!" So this morning I smiled at him and shouted "God loves you! Be happy!"
And he smiled and waved, and blessedly shut up.
