"They don't understand that a majority of the marchers are bilingual but prefer communicating in their dominant language"
First, many of them are NOT bilingual. Second, calling Spanish their "dominant" language its part of the problem. They're here, they want to stay, their dominant language should be ENGLISH!!
My immigrant grandparents were forbidden to speak anything other than English, even at home. They were Americans now.
That's awesome hoody! That's how it should be.
