Basically yes. No one gives a rats hairy ass about what some random dbag Bills fan says (except apparently Watkins since it was about him) so no one pays attention to it. But a lot of people care about what Watkins says, otherwise they wouldn't be following his twitter, or instagram or whatever that post was on. So people react to Watkins when he posts like a dbag.
You don't have to love it, but that's the way it is. I suspect there is a way he could block specific dbags, or everyone, from posting to him.
