Khloe Kardashian and brother Rob Kardashian have always been close. In fact, Rob is living with his sister as he works to battle what most believe is depression. Rob Kardashian has gained a lot of weight in the past year or so but in recent months has worked hard to take it off. He all but disappeared from social media, but is making a slow-but-steady return.

On Thursday night, Rob posted a short video of the late Malcolm X on Instagram that some fellow Instagram users misunderstood. They believed that Rob was comparing himself to the late political figure. That’s when Khloe Kardashian came to his rescue.

“He is not comparing himself you judgmental f–k,” Khloé Kardashian wrote back to one of the commenters. “Where did he say he was?!?! He’s simply admiring another man’s wisdom, strength and courage…Can’t one admire another without the stones being thrown. Chill out. Get off my brothers page.”

The user, who calls him or herself @annofscotland likely explained the comment, prompting Khloe Kardashian to behave in a much less harsh manner. She wrote back to the commenter.

“@annofscotland happy to hear that! He gets criticized for being too private and then when he decides to get back on social media he gets attacked,” Khloé wrote the second time around.

“Damned if you do and damned if you don’t. Let’s uplift one another and not assume,” Khloe Kardashian added. “Let’s all root for Rob.”

Fans loved that notion, and many jumped on board in support of Rob Kardashian.

How do you suppose Rob Kardashian feels about Khloe Kardashian interjecting herself into his social media affairs? Is he appreciative of his sister sticking up for him or might he prefer to fight his own battles instead?
