From the context it was obviously an offhanded joke,

Ah so that's the thread in question. Was wondering what post it was and honestly, I suspected that one of being rage bait.

The original image seemed like it was missing context so I figured OP was gonna come swinging in later against any comments saying it was extreme with the additional context.

And yes, out of context I thought it was a bit extreme. I don't necessarily agree with what the first person in the image said although that's a complex topic that deserves a much lengthier discussion, but just randomly having someone tell them that they're a creep who deserves to be tased is fairly extreme without any additional context. Keep in mind, I have no idea who the individual is or what they've done.
