Marrying an Asian person is different from sexually fetishizing Asians as a category, so I don't think Cage or Soros are relevant here.

But we can’t be certain they did not entertain a fetish before their marriages...

Question is, does it matter? What if someone likes BBW and fetishizes it, do we care? If they then marry a BBW is it no longer a fetish?

Personally, I don't care about other people's sexual preferences ans I don't see why anyone should.

The one argument you can make against fetishizing a group of people is that it's reducing members of that group to fetish objects.

So if you're an Asian woman trying to date seriously, you'll get a bunch of white men who only care you're Asian and nothing else.

I don't know how much of an issue that is in practice (and I'm sure it's different in diff parts of the world).

Hang on, presumably you're now framing this as a US thing. How do we know the demand in the US comes disproportionately from white men, is that in the stats[1]? OKCupid seems to tell a diff story.
