Do some Veteran's Groups on Social Media accurately represent the Veteran Community?

While wandering through the interwebs and some social media sites, I have come across quite a few that claim to be "Veteran Friendly", however some of the stuff I see on the sites is beyond outrageous and to a degree I feel personifies what civilians fear about Veterans. An example would be claiming the title "dysfunctional veteran", along with folks flipping the bird and some armed to the teeth.

Don't get me wrong, I am all for freedom of speech and the Second Amendment. But does this accurately represent the feelings of the majority of the Veteran Community?
