Avengers Fanfic/Fanworks Search Community

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.)

With the six Avengers and all the people around them that be counted as part of the team or support, somebody might have used this plot line for this fandom.  I read this originally in an X-Files story.  I do remember that it had the central four characters: Mulder, Scully, Skinner, and Krycek, but it's been several years since I read it so I don't remember who dumped who to be with who, so I'll just refer to any four as A, B, C, and D.

A and B are dating/sleeping together/living together, whichever.  A is totally in love with B.  C, who has been away/missing/out of the picture, suddenly shows back up.  B and C used to be together and B is still in love with C.  B throws A over to get back with C.  A is broken hearted but leaves quietly, knowing he was second choice anyway.  After a short, but intense time, D pops back in the picture. C is in love with D, only getting with B because D wasn't around.  C leaves B for D, same as B did to A.  After a length of time, D decides he cannot deal with C's intensity/crazyness/neediness/whatever and ends the relationship.  Brokenhearted, C goes back to B, who is ready to dump A again.  (Actually, I think somewhere along the line the dumped one get fed up with the whole thing and tells the returning ex to shove it.)  Get the picture?  I hope this isn't as confusing to you as it's becoming to me.  It's basically a vicious game of musical lovers, with uncaring lovers and broken hearts all around.

Goddess, I really don't want to tag every possible pairing that can come out of this...
