a) not everyone on this forum is from the US

b) 2 things can be objectively bad at the same time. It should be ok to criticize Qatar from within the US without needing to preface your nationality.

No, but Y Combinator is in the US. If these things are really so objectionable I'd expect there should be boycotting of HN along with boycotting of Qatar.

The OP submission has nothing to do with slavery in the first place. If your gonna bring up irrelevant moral issues, they should at least be ones that are unique.

This is whataboutism.

Every critic of the USA is whataboutism. USA just has to start a critique first, and then yell "whataboutism" when confronted with double standards. Problem solved.

But this article has nothing to do with the USA. We’re here discussing Qatar, and invoking America adds nothing to the conversation. This is the problem with whataboutism: it is the attempt to shut down the discussion of a grievance, by pointing out a grievance done elsewhere.

Reading the parent's comment with the most charitable assumption, the parent wishes to discuss the issues of both countries.
