To be fair, you don't have to refer to them as "Indians". Most serious academic anthropologists would refrain from doing so, preferring Native American instead. So to label them as "Indians" yourself and then to state that "it's not hard to see how there are misconceptions about them if they're still referred to as 'Indians'" is a bit disingenuous. I'm sure there are misconceptions but I don't take as evidence the fact that you chose to call them "Indians".
