Can you honestly tell the difference?

Mexican=Mixture of Sub Saharan Negroid, Native American Mongolid, and Spanish Caucisoid in various different mixtures.

White=Light Skinned Caucasoid, with the greatest variation in hair and eye colors.

It's literally not even close to the same thing.

They do have a lot of white in them. Here is the reality:

Google search involving census information:

The federal government officially categorizes people with origins in Lebanon, Iran, Egypt and other countries in the MENA region as white.

The people of India are predominantly Caucasoid. Their features, hair texture, hairiness, the shape of the nose, mouth, and so on, are all distinctly Caucasoid. It is only in some of the far, out-of-the-way places of India, as in this country, that you find certain traces of other races.

In the United States, a white Hispanic or Latino is an individual who is of full or partial Hispanic or Latino descent, the largest group being white Mexican Americans.

White Hispanic and Latino Americans.

Asians and whites have a lot more in common genetically than they do with blacks/africans.

OP Mexico has a huge diversity in the way the people look. Some people look native because they never mixed with the Spanish conquistadors (aka they escaped the rape), others are actually just white because the British had some settlements and kept it all white. There’s a place in Mexico called mineral del monte where a British settlement existed due to the mines being rich in silver. Many of them never mixed with the locals, but of course all speak Spanish now (English there basically died away), but are white. It’s pretty cool to see actually.

There are even legitimate black Mexicans. Like African black, not just dark skinned natives.

Theres actually a group of people that get called whitexicans in Mexico.

Skin color isn't the main issue, but the complain is mainly the bubbled out of touch attitude towards poverty in the country... and mostly that people happen to be white and obviously more wealthy than average

What about Oaxacans, they're like the Sicilians of Mexico
