Yes I am aware of the the Spanish roots as they brought cattle to the americas and taught their techniques to the indigenous peoples.
These vaqueros then turned it into a lifestyle over a couple hundreds of years, As the wiki says “…and extensively developed in
Mexico from a methodology brought to
the Americas from
Spain. The vaquero became the foundation for the North American
cowboy, in
Northern Mexico,
Southwestern United States, and
Western Canada.”
I could have been more diplomatic as no one was co-opting anyone. The comment is really just an attention getter, but the idea of the cowboy being a uniquely white american tradition is hogwash.
The real truth is the part of your post I quoted. People went out west to make a life and they learned how to from people that taught them knowledge that has been learned and advanced upon over hundreds of years. We are all one and the more we help each other and teach each other the greater we will all be.
We should be focusing on what unites us and brings us together instead of focusing on our differences and seeing people from other countries as almost a different life form.
The southwest is a good example.
You got cattle ranching
You got Tex mex food using many spices brought from India
You got tejano and norteno born out of the influence of the German and polish peoples that brought the accordion and polkas
