It seems like bullies are taking turns to bully the Kardashian family one by one. First, Kim, Kourtney and Khloe were called "fame wh**es", then Bruce Jenner (now Caitlin Jenner), whose struggle with gender identity was mocked online, and now it is Rob Kardashian, who is apparently "too fat".

In fact, Rob Kardashian became a trending topic on Twitter in the US, after reports suggested that he looked like he had gained weight when paparazzi snapped him when he went out to get a burger. 

Many people called him out with sadistic jokes and cruel remarks: 

Rob Kardashian is still shaped like a soccer mom of 4 kids in an unhappy marriage

Rob kardashian has ALL THE ACCESS IN THE WORLD to get his FATASS in shape , I don't feel sorry for him anymore he just lazy n nasty now

U can't live with the kardashian sisters and be of sane mind, look at what's happening to Bruce and now Rob kardashian.

Meanwhile, there are people- "Keepin Up with the Kardashians" fans and otherwise - who make us believe there is still goodness and kindness in the world:

Jesus Christ, stop being so cruel towards Rob Kardashian. He doesn't need your validation for his existence. Don't be hateful!! -Eve Aléxandra ‏(@EveAlexandra21)

rob kardashian actually feels the need to hide from society and rarely shows himself and you find humor in that? you're disgusting tbh...if you're making jokes about rob kardashian's weight then seriously take time and reevaluate your life- talk about something that matters. -britt ‏(@almightyniaIl)

Rob Kardashian actually comes out once a couple of months because he is insecure and ya'll think that's funny. - KKKARENNN ‏(@leftxeye)

y'all claim to be body positive but are so quick to fat shame rob kardashian smh - (❁´◡'❁)*✲ ‏(@fridavsthem)

So pathetic that 9 people lost their lives in a place they should have been safe, but what's trending is Rob Kardashian to mock his weight - Melissa ‏(@Tardy4daParty)

Rob's younger stepsister Kylie is also not new to cyber bullying, and in a series of snapchat videos the youngest Jenner explained her ordeal with the same. "I've been bullied since I've been 9, from the whole world it feels like sometimes...And I think that I've done a really great job at handling all of this," she speaks barely above a whisper.

"There's bullies everywhere," she adds. "This is just a little late Snapchat to tell whoever with their own bullies that the only opinion that really matters is yours and to never change." However she clarifies that it is not a pity party: "Don't get it twisted...This is for the others with bullies out there to know that you're not alone."
