Preserved? Yes, of course. Flaunted, under the guise of preservation? I wouldn't think so, but then, I'm not "everybody". Most often, it's a particular set of lyrics that people object to, but sometimes the melody itself carries associations that some people find objectionable. Take "Garry Owen" as an example - a great tune before it was adopted as a regimental air by the 7th Cavalry, and still a great tune, but there are folks who object to it because of its association (in their minds, at least) with the undeniably racist attitudes of the US government as regarded the pre-Columbian settlers of the continent. It wasn't adopted by the regiment "because" it was racist, but because it was a popular tune that reflected the ethnic heritage of a large part of the men in the unit. End of oration. I'll put the soapbox back in the closet (until the next time, anyway).
