I don't see any racism, but the homophobia is pretty evident. Presuming the name of the alien race being "Buggers" is just an unfortunate coincidence and not deliberate, that still leaves...
Spoiler for "Children of the Mind":
Spoiler: Ender's long filibusters on how having children and a faithful heterosexual marriage is the ultimate expression of a happy life and duty as a human being. His ultimate marriage to Novinha.
Spoiler for the "Shadow" series with Bean:
Spoiler: Anton the geneticist, who is self-described as interested in men, not women, deciding that ultimately he must find a woman and have a family as his duty as a human being. And he does, despite having no sexual interest in her. There's also a none-too-subtle affiliation of homosexuality with Soviet Russia - he notes that "those like myself" were encouraged to be gay as their duty to the State (population control).
In other words, being gay is alien/Other, traitorous to humanity, and Communist.
That being said, Ender's Game is a good book. Especially for gifted children to read.
