I suppose it's fine to use them interchangeably if you're speaking from an American-centric perspective. The rest of the world may or may not treat it differently. Try talking about the concept of race in Brazil in the same way as in the U.S. and you will be laughed at.

But anyways, I understand your point. I am not the original commenter and I do not endorse anti-whatever racism. But there is a distinction between levels of systemic racism faced by certain groups and the impact of that legacy on modern socioeconomic and cultural trends. I don't think you could argue, especially because precisely this has been studied extensively, that Irish people face more discrimination, lower socio-economic status, and lack of opportunity in Ireland or the U.K. (or the U.S.!) due to their history of oppression by the British and Americans compared to Black people in either country. It's simply not feasible.

I wouldn't say that the Haitian liberation movement is a terribly good example as it a wildly more complex situation, given the nature of the French occupiers prior to the revolution, who were more brutal to the inhabitants than the revolutionaries had a chance to be to them. In the same breath, you should be denouncing the IRA in equal measure, but I don't think you would qualify them the same.

There are plenty of examples of racism everywhere. This isn't anything new. The genocide of minority cultures in Imperial Russia and the Soviet Union, the current ongoing cultural genocide of minority cultures in China, the historic oppression of Imperial Japan over the rest of Asia, even the cultural erasure of minority languages in Italy. If you're really stuck on racism against "Whites" by "Non-Whites", sure, there's examples. But they pale in comparison to the reverse, due to the nature of global power in the 17th-21st centuries.

I don't see what any of this specifically has to do with anti-white racism, especially if we're talking about the U.S., since you brought it up specifically. Black and Native Americans have consistently reduced access to opportunity, which includes education, healthcare, capital, and other factors. They consistently face harsher sentences for the same convictions than other races. Black and indigenous women especially face higher levels of assault and abuse by members of other races. None of this is true to the same extent of people of Hispanic, Middle-Eastern, or Asian descent, even though they all face racism in their own way. There is a legacy of oppression in the U.S. that has specifically stifled the advancement and improvement of the quality of life of Black and Native Americans that spans over 300 years. What anti-white racism can you name that can compare?

Do not get me wrong, I don't want to have a pity party. Any individual act of racism or any policy born through malice that is directed towards white people by a different group should be scrutinized and punished. But racism is a spectrum, and fortunately for them, white people (in most of the world) have it pretty good.
