That’s the experience of an economics student, Vedran Vuk, who wrote an article contending that “sweatshops” are not the unmitigated evil that leftist activists say they are. After making his argument, he was swamped with nasty email. He writes about it here.

As Thomas Sowell has written, before one can be a partisan of the poor, he must first be a partisan of the truth. The trouble with the leftist activists is that they ignore the truth that the world does not usually provide quick fixes for them to order into place to solve the problems they perceive. Point the truth out and … well you know what happens to messengers who bring unwanted news.
