Martha Plimpton makes us crack up on Raising Hope.
But the veteran actress saw nothing to laugh about this weekend after photos of Julianne Hough in blackface went viral.
The Dancing with the Stars professional was merely dressed as a character from Orange is the New Black, but that didn't matter to Plimpton.
"It's not hard," Plimpton Tweeted. "White people: Do not wear blackface. Life will still be okay if you don't ever, ever, ever wear blackface. OKAY? GREAT."
Following some online backlash ("Five hours later, it's crazy racist trolls all over my timeline. Ugh."), the occasional The Good Wife guest star elaborated on her opinion:
"I don't respond to every stupid thing every idiot does. Just the stuff I think matters. Blackface matters."
Plimpton then weighed in on the nature of fame and got pretty personal with Hough.
"Can we use this moment additionally to also recognize that elevating morons to celebrity status does not help the world in any way? Ever?" she wrote. "Not every pretty person with two legs needs to be famous. People who DO things, okay. It just makes nonsense like this inevitable."
Ouch. Easy there, Martha.
The actress did finally relent, acknowledging Hough's apology for the outfit and concluding:
"I do feel bad for calling @juliannehough a moron. That was mean. Ugh. I'm sorry. Glad she acknowledged her mistake. I should, too."
What do YOU think of Hough donning blackface for Halloween?
