It's possible to appreciate the good in Western art, and the positive contribution is has made, and its many accomplishments, without being blind to its very significant problems and contradictions, and the damage it has been a part of. Appreciating it does not automatically mean that you swallow it whole, or that you look down on the art of other cultures or feel superior to them.
I think that probably the majority of people are not making the dogmatic assumption you assume they are, just because they say they enjoy Michelangelo's work. Most people are a bit more thoughtful than that.
