In the two months since he was found guilty of using a webcam to spy on his roommate, Dharun Ravi has gone from being a symbol of antigay bias to being something of a folk hero, with rallies of his supporters urging the court to “free Dharun.”

What may be most surprising is how many of those arguing in his defense are prominent gay rights advocates.

With Mr. Ravi scheduled to be sentenced on Monday, many of them have argued against the prison term prosecutors have recommended. They say that Mr. Ravi is being punished for the suicide of his roommate, Tyler Clementi, although he was not charged in it, and that pinning blame on him ignores the complicated social pressures that drive gay teenagers to kill themselves.

As repugnant as his behavior was, they say, it was not the blatantly bigoted or threatening actions that typically define hate crimes. Some fear that a sentence that overreaches might provide tinder to antigay sentiment — a New Jersey talk-radio host complained soon after the verdict of the “gay lobby” railroading Mr. Ravi.
