Why do people look down upon teenaged fathers?

People ume that I don't care about my son, and that I'm just another teen-aged father who runs away from his responsibilities, and it just pisses me off. Just because I'm nineteen, and I have a son DOES NOT mean that I'm running off and leaving my son with my wife. People ume my wife and I are on welfare, and when I go out with my son, people look at me, and I hear people scoff, "Looks like another teenage couple we have to pay for." Damn it, I work three jobs to get enough money to keep my son, while my wife stays at home and takes online cles so we can have a better future for our child. I've been working so hard to keep my baby boy, even before he was born, and I don't understand why I have to put up with these judgmental people. Why do people look down on teen-aged fathers, because I'm so sick of being judged all the time? Why do people look down on me, even when they don't know what the heck I've gone through to keep my son? I'm sorry for ranting, but I'm just pissed off right now.
