And as usual you can supply no evidence contrary to my facts.
Where do you live? Spokane? Oslo?
You clearly know nothing of the Southwest, or the settlement of it by the Americans.
While you may think that "before 1975 no one spoke Spanish in public in the southwest" I was there and yes they did.
We were learning Spanish at the time so our ear was tuned to hear it and hear it we did.
Perhaps you were not paying attention or it just swept by you without you noting it.
According to my husband in Killeen Texas in 1960 you heard both English and Spanish in the town.
So I am sorry but what you are stating is simply not true.
And no amount of your attempt to disregard reality and pathetic attempts to change the subject by insulting me will change what happened.
