Seriously, what kind of laughable horse**** are you trying to flog here in your pathetic attempts at demonizing and hounding the homeless?
"Social contract governing NPS"? I can't decide what's more hilarious: the ridiculous Angry White Man bile you keep spewing, or the sheer ignorance you clearly have of political and legal theory in your attempts to justify a position steeped in hate.
Or, for that matter, the fact that you're actually suggesting police state measures to stomp the problem of homelessness under the table. After all, after you hound all the homeless from NPS, where do you really going to think they're going to go? And how many more locked gates will we end up with as your ludicrous plan stumbles towards it's (il)logical conclusion?
Like I said, it really does take a special kind of loser to go after the most vulnerable among us with the degree of contempt you clearly have. So congratulations on your remarkable achievement.
