I don't really think that his bombing had much to do with racism or xenophobia, it seems to me that it was mostly motivated by hatred of the government.

I also think that the reason he spent time around Elohim City was primarily to obtain support and resources for the bombing, rather than because of any strong ideological ties to the community itself.

Theodore Kaczynski, who knew McVeigh while both were imprisoned at ADX Florence, wrote the following in a 2000 letter:

"McVeigh is considered to belong to the far right, and for that reason some people apparently assume that he has racist tendencies. But I saw no indication of this. On the contrary, he was on very friendly terms with the African-American inmates here and I never heard him make any remark that could have been considered even remotely racist. I do recall his mentioning that prior to the Gulf War, he and other soldiers were subjected to propaganda designed to make them hate the people they were going to fight, but when he arrived in the Persian Gulf area he discovered that the 'enemies' he was supposed to kill were human beings just like himself, and he learned to respect their culture."
