Arun Thiruvengadam discusses a Gail Omvedt article (emphasis mine):

In comparison with race, though, it is superficially easy to avoid dealing with caste: it is not so easily visible as race is, though both are equally social and not biological factors. There is a good deal of social interaction directed at understanding the other’s caste, but these are less obvious and visible. As a result, a superficial ‘passing’ is much easier, particularly for employment, if not for more personal issues such as marriage. Yet the scars of caste remain, of this there is no doubt. What is needed is more informed discussion and debate, not a closing of eyes, ears and mouths to mimic the monkey reaction to reality.

I’d always agree with Gail Omvedt.
