Martin Luther King Jr. did speeches, marches & civil disobedience. He was a professional complainer.
Mr. T actually held a job before he landed the role of B.A. Baracus on "The A-Team". And B.A. was the perfect role model for any boy or man. He was very physically fit and a mechanical genius. Any time the team needed some huge contraption improvised in a hurry, B.A. put it together.
B.A. didn't smoke, didn't drink (except milk), didn't swear, didn't start fights (just finished them when necessary) and had a huge soft spot for kids in tough situations.
And B.A. wasn't the team's "black guy". The shows' plots never revolved around his skin color, just the content of his character (which was considerable and admirable).
So, yeah, if I had a son, I'd rather have him grow up to be like Mr. T.
