Anthony Mackie is a good dude. I think a lot of people also forget that he played a gay character in that indie film from like 20 years ago, Brother to Brother. I remember watching it and just being happy that there was a black gay character portrayed on the screen.
I agree with his assessment. While it's easy to look at things through a queer or homoerotic lens, I definitely don't think that's the case with these two characters. Although it's fun to joke around with it. I actually want to see more carefree, sensitive straight male friends. Because to associate it automatically with homosexuality is just as detrimental. Men can love each other and be affectionate in a platonic way and have it not be sexual.
