This is probably the least "wtf" thing I've seen from him show up on twitter. No one would bat an eye about BDSM shyt showing up in a "white" show. Hell, it went mainstream with Fifty Shades Of Grey. It shouldn't be hard to understand television shows and films can cover a variety of topics. Who cares man.
Why this scene means he is a "sick" person...I have no idea. Chill out
