Christian activists who infiltrated Toronto Pride pretending to be "gay zombies" are being sued for more than $100 million.

Toronto lawyer Douglas Elliott has filed a $104 million class-action suit against Bill Whatcott, a longtime opponent of LGBT equality, reproductive rights and other progressive causes. Elliott is asking a judge to prevent Whatcott from sneaking into any more Pride events and to order him to disclose his financial records so the source of his backing can be ascertained.

“He says he doesn’t have any money. So we want to find out who is paying for this. Who is writing the checks?” Elliott told the Star.

“This is a unique way of dealing with hate speech. It hasn’t been done before, but I have not been very satisfied with what has been happening up until now.”

Whatcott and his Christian cronies donned green bodysuits before joining the procession last month, where they proclaimed they were "gay pothead zombies."

While it looked like they were passing out free condoms, the undercover haters were actually handing out Bible tracts revealing “the physical and spiritual dangers of homosexual practices" and depicting graphic images of people suffering from AIDS.

Whatcott, who paid $100 to register "Gay Zombies Cannabis Consumers Association" in the parade, said it was much more effective than if he didn't wear a disguise.

"If you try to give out a Gospel pamphlet, they swear at you and throw slushies on your forehead," he explained. "But give them some whackadoodle thing that looks like a condom and they really can’t grab it fast enough. I had 3,000 out in 20 minutes."

He told Daily Extra "the poor homosexuals" were really angry at God, not him. "They should have welcomed me in their parade as a much needed truth-teller."

“I think my flyers are the most loving and useful and health-promoting literature that the homosexual Pride parade could have," he added. "So really, if they were going to embrace diversity, they ought to embrace me.”

In October 2011, he appeared before the Supreme Court of Canada to defend his right to hand out anti-gay pamphlets on college campuses. The court ruled that although Bible passages and principles can be reasonably advanced in public discourse, extreme manifestations of the emotion described by the words "detestation" and "vilification" cannot.
