I see immature posts on Facebook everyday that are worse than the girl's post in this video. I could just imagine what this dad would do to those kids.
In my opinion, I think what he did is great. From a kids standpoint, I could never imagine being that kid and posting such a dumb*ss thing on Facebook where EVERYONE can see it. If you are one that would or has posted such a disrespectful and immature thing then I would probably think twice...
