People who confuse culturalism with racism are a bane.

There are various conceptions of race, but each involves an attribute fixed at birth (though this attribute may be more extrinsic that intrinsic), no matter the culture in which one is raised.

Racisms are doctrines that race (however conceived) is a determinant of merit.

To be disrespectful of the positive or innocuous aspects of some culture is a bad thing, to be sure, but not everything about every culture is good, and some things about some cultures are horrible (eg: clitoridectomy).
