Denis Leary seemed to have mellowed out the past few years, focusing on charity work and his surprisingly good FX show Rescue Me. But his inner loud mouth is back and it’s just begging for Jenny McCarthy to come kick it’s ass. Denis has made some harsh comments about modern medicine, and modern parenting (or lack thereof) in his new book, “Why We Suck: A Feel-Good Guide to Staying Fat, Loud, Lazy and Stupid.”

Leary writes,”There is a huge boom in autism right now because inattentive mothers and competitive dads want an explanation for why their dumb-ass kids can’t compete academically, so they throw money into the happy laps of shrinks . . . to get back diagnoses that help explain away the deficiencies of their junior morons. I don’t give a [bleep] what these crackerjack whack jobs tell you - yer kid is NOT autistic. He’s just stupid. Or lazy. Or both.”

The Autism Society of America is not amused: “For Mr. Leary to suggest that families or doctors conspire to falsely diagnose autism is ridiculous . . . [His] remarks reflect the same misconceptions of autism being caused by bad or unemotional parenting that were held over 50 years ago.” Way to go Leary…can of worms now open.
