Weighing into a controversy kicked off by TV personality Ellen Degeneres, who came under fire for schmoozing it up with former President George W. Bush at a football game last weekend, Ruffalo insisted no quarter or kindness should be offered to perpetrators of heinous war crimes until they face consequences, including Bush.

“Sorry, until George W. Bush is brought to justice for the crimes of the Iraq War, (including American-lead torture, Iraqi deaths & displacement, and the deep scars—emotional & otherwise—inflicted on our military that served his folly), we can’t even begin to talk about kindness,” the actor of Incredible Hulk fame tweeted.

While some online were appreciative of the anti-Bush sentiment, many wondered aloud why similar treatment was rarely afforded to Bush’s successor, Barack Obama, who is largely given a pass despite pursuing – in some cases escalating – many of the same policies for which Bush is condemned today.
