What do these people fear or hate about Indians protesting about Indian issues?
Fascists know Liberals are sympathetic to Native American causes, so they reflexively oppose anything that Indians or their allies do or say. Its that simple, these privileged little prep school punks don't have a position or an opinion, they just don't like people who aren't like them. And they really loathe anyone who understands that about them. This is the mentality that coined the phrase "crisis actors" for kids who had the audacity to protest (publicly and effectively) that they were being gunned down in their own schools.
Can you come up with a better definition for 'fascist'? Can you come up with a better definition for 'racist'?
