Pap is an outwardly angry individual. What does his discussion about the government and race lead to believe about Pap?

Once at the cabin, Pap proceeds to drunkenly curse everyone he has ever met and spends a significant part of his tirade criticizing the government. Pap questions how the govenment can keep a father's son away from him. 

Call this a govment! why, just look at it and see what it's like. Here's the law a-standing ready to take a man's son away from him—a man's own son, which he has had all the trouble and all the anxiety and all the expense of raising. Yes, just as that man has got that son raised at last, and ready to go to work and begin to do suthin' for him and give him a rest, the law up and goes for him. And they call that govment!
