Sam is literally the only avenger we know anything about there family life, that doesn't involve potential other meta or super hero's.
MCU 1st character with actual DEPTH, if this show doesn't do anything for you then it's clear you only want explosions, actions, super powers, and conspiracy theories
All those things that happen go into why SAM feels like he has to go forward and at lest try to be captain America, it also shows why he's worthy of being mantle captain america and US Agent wasn't.
And Isiah's viewpoint is how MANY if not most black people feel about america, when he told Sam no self respecting black man would pick up that shield I felt that. Imagine your great great gandfather that was a slave or war vet gets mistreated and locked up and you tell them you are going to serve your represent america and they tell you that.. It takes a certain type of person to go forward and still want to protect, represent and change things.
The black super soldier isn't something they made up it's literally from the comic's. This was the perfect time to acknowledge it in the MCU, to skip over it, and then do the whole US agent plot line would be very whack. If you gonna touch on pretty much all things cap throw all the relevant cap stuff in there (more soon coming with the black widow movie I'm sure)
Comments like this tell me you either aint black or you black and feel you gotta push back at everything that touches on black subjects.
The boat storyline is common place as someone that says here in louisiana, tug boats and finishing boats here in louisiana are some peoples livelihood.
Falcon getting stopped by the cops and then not recognizing him is common place also among black people getting stopped and cops not recognizing them until they get some id or someone points it out.
The black cap story I already mentioned.
