This isn't just mindless vitriol aimed at a kitten, it does have a purpose - and that's to promote the latest film Channing Tatum is in, that being Quentin Tarantino's Hateful Eight. Ergo, having Channing Tatum say Eight Hateful things to the cutest little creature imaginable makes perfect sense now. It's all about context.
The head on the kitten when Channing first enters the set is probably the highpoint, along with the phrase "Dude, you eat out your own ***hole every single day."
