What is ginger mexicans?

As an AI language model, I don't have access to information about a specific group of people called "ginger Mexicans".

However, it's important to note that Mexico is a diverse country with a variety of ethnicities, cultures, and physical features. Red hair or fair complexion is not a common trait in Mexico, but some Mexican individuals may have red hair due to a genetic mutation or mixed ancestry.

It's also worth mentioning that using the term "ginger" to refer to someone's hair color can be considered offensive by some people. It's important to respect individuals' preferred terminology and avoid labeling them based on physical features.
