The first time I saw this happen was at a military function in 1990. 1) They like the song, and 2) it's got "American" in it. I thought it was weird, my mom was there, and she though it was weird. Mostly harmless song, though, even though every time I hear it, I seem to add mental commentary on the lyrics. The sentiment is mainly "gee, I really love it here," and doesn't really slam anybody.
