Criticisms of the Cuban government are absolutely independent of criticisms of individual Cubans like myself. If another Cuban person felt that they were being individually criticized when other people criticize Cuba, I'd tell them they need to learn to distinguish between the two - it's not the responsibility of the public to avoid any criticism of the Cuban government. This isn't an attempt to "deflect the discussion", it's using another country as an example to make it clear that this is a distinction we're perfectly capable of making for other ethnic group.
For that matter, sincere requests for clarification are not immediately followed by attempts to dismiss the underlying concern as invalid. This inherently makes the request insincere.
Remember, allegations of "dog-whistles" are really just saying "I'm assuming other people are implying XYZ." My conservative relatives think words like "diversity" or "inclusion" are dog-whistles for anti-white discrimination. They're earnest when they say the feel attacked, but that's entirely on account of their own assumptions and does not indicate any actual racism. If doom2 wants to make point, they should actually explain what they witnessed that was bigoted or hateful - don't just allege "dog-whistling" and do nothing to substantiate that claim.
The above commenter’s experiences will ring true for many Chinese living in the US, because we are the ones who experience and are impacted by sinophobia (this can also extend to other E/SEA diaspora to an extent). Whereas the commenters claiming that we’re biased or influenced by propaganda, as if they are uniquely exempt from such things, are not.
