"Brooklyn Nine-Nine" actor Terry Crews crossed the line this weekend.

He said sorry on Sunday after tweeting that the children of same-sex parents would be "severely malnourished" when it comes to love.

The conversation that prompted the apology began more than a week earlier when Crews reacted to an opinion piece in the New York Times by human rights lawyer Derecka PurnelI. Crews initially took issue with Purnell, a woman, writing a piece called “Why Does Obama Scold Black Boys?"

"Another thing that bothers me is that this OP-ED was written by a WOMAN about how boys should be taught to grow into successful young men," he wrote. "How would she know?"

Crews, who has spoken out about his own sexual assault and has become an activist in the #MeToo movement, took heat from Twitter users who said that women have a right to speak when it comes to raising men.

Over the next week, the conversation began to evolve over the roles mothers and fathers play in their children's lives.

"I've reiterated many times that same sex couples and single parents can successfully raise a child," Crews tweeted Saturday. "But I believe paternal AND maternal love are like vitamins and minerals to humanity. No matter where you get that paternal and maternal love. MY purpose is to give paternal love."

A Twitter user replied, "love is not gendered. a child will not starve with only one gender loving them."

Crews's now-deleted response to the tweet was, "But they will be severely malnourished."

On Sunday, he apologized for the eyebrow-raising comment.

"I apologize to anyone who was hurt by my 'severely malnourished' tweet. It was in response to someone who said that kids wouldn't 'starve,'" he tweeted. "It was poorly worded so I deleted it."
