Methinks he doth protest (but not too much)

Dressed in a suit and tie, environmentalist Glenn MacIntosh didn't look like a protester.

That's probably why he managed to get off a few lines attacking Dalton McGuinty on Monday as the premier announced Ontario's target for reducing greenhouse gas emissions.

"It's one thing to say it, it's another thing to do it," the 39-year-old founder of Ecosanity.org yelled as he was frog-marched out of a convention hall by security officials.

After receiving a warning from police and being released, MacIntosh admitted the event was his debut "shout down" of a politician, prompted by concerns that leaders must take more aggressive action to fight climate change.

While such demonstrations were relatively common during the tumultuous years Mike Harris's Progressive Conservatives were in power, it was one of the few times McGuinty has been interrupted in such a fashion.

Still, the premier didn't appear fazed by the outburst.

"I'm proud of our democracy and I support that gentleman's right to make his point," McGuinty said to applause from the audience.
