Yes. The USA is good at Baseball, so the crooked white old men on the crooked IOC take it away. The USA totally dominates Women's Softball, so..... they take it away, again... Hey, I'm seeing a trend. If the rest of the world hadn't caught up a bit with the USA in basketball, trust me... the IOC would have stripped that game from the games long ago.
And what the hell happened to their 'investigation' into the Chinese 'Women' who won medals at the Bejing games, oh right, they were Chinese so it's okay. You think that if they were from the USA (though us in the US are too high profile to fake birth certificates that the IOC wouldn't have taken the medals away with barely any investigation. But the we're (the USA) evil in their eyes, and the rest of the world is somehow better. Trust me. The 'real' part of Rio is no way in hell better in any way than the 'Real' part of Chicago.
So, to make a long post short. Yes, the IOC is rabidly Anti-United States of America. (Though, another poster was right, technically they're not Anti-American 'cause they chose Rio) just Anti-USA.
