The team facing racism
I've seen many stories dealing with homophobia (and could always do with a new one, hint hint), but don't think I've come across any that deals with racism. Either against blacks (Sam and Rhodey), or against Natasha for being Russian or Thor for being from 'some place else'. Distrust either within the team, from inside Shield, or the press and/or the public. Okay, I have seen, once or twice, the press showing suspicion of the Russian Natasha, but just in passing, as a passing gossipy type headline and not in any actions or open hostility. I've never seen any stories where there is objections to have Iron Patriot/War Machine or Falcon on the team. Maybe someone questioning how Captain American, and American Icon, can stand working with those black boys or that girl...she's just eye candy yadda yadda yadda. Or even having the 'token girl' on the team, either Natasha or Hill. (I just can not see anyone getting in Fury's face, calling him a nig...nope, can't see that happing.)
