The "racist" accusations come from Tumblr, where they've decided that the Maximoffs have been "whitewashed" because they're not Roma-Jewish. They never were, in the comics - they were generic white characters who were later retconned into being Magneto's kids, and he was retconned into being Jewish, etc. It's not really whitewashing if the characters have always been portrayed as white, but you know Tumblr.
Iron Man's joke was completely in character. He's a smart jerk. If he actually meant that he wanted to force women to have sex with him, it would make him a bad guy (more so) but as it stands he's just a guy who made a tasteless joke. Again, people often confuse a character saying something with the author believing it's totally fine.
And yeah, Natasha was saying she's a monster because she was turned into a killer, not because she can't have children. Forced sterilization was part of the process of turning her into a killer. But it's a big leap from there to "Joss Whedon thinks women who don't have babies are monsters."
Sometimes when people are taught to recognize bad or racist or sexist tropes in popular culture - and that's not a bad thing to recognize - they jump to deciding that all uses of a trope are illegitimate, or that characters must never do anything that reinforces negative stereotypes. So some people go from "too many movies have women who need to be rescued by men" (true) to "it's bad that Natasha got captured and needed Bruce to break her out." That's not how art works.
