This is what a lot of diaspora are like when a country has had a western friendly puppet regime overthrown.

The people who left tend were often in a privileged position under the previous regime and the bitterness at having their privilege revoked often echoes through the generations.

They might feign concern for human rights when the regime they hate is violating them (i saw a lot of that when the alleged killing of tens of thousands of protestors) but it's the bitterness of lost privilege which truly drives them.

Ive seen it with Cubans, Venezuelans, Angolans, even the odd Russian.
