What you're saying, albeit you managed at least a bit of tact, is that Japanese internment and the genocide of Native Americans don't count as military-assisted oppression because "it was just the minorities".

The genocide of native Americans, slavery, segregation, and Japanese internment were all carried out consistently with the desires of the relevant polity of the time. When George Wallace stood in front of the school house and shouted "segregation now, segregation tomorrow, segregation forever" he didn't do it to try and impose his idiosyncratic view of the world. He did it because he knew it would endear him to "the people" of Alabama.
Well then, I don't care much for your notion of "democracy", and don't particularly understand why it would be worth defending or even necessarily better than minority rule in the first place.
Most reasonable definitions of democracy delineate between mere mob rule, and democracy as a governmental philosophy (including aspects like equality before the law).
The word "minority" conjures up images of the oppressed, but through most of human history, the minority have been the oppressors. The majority were, historically, ruled by the will of a minority of people that made up royal families, etc. Saudi Arabia, for example, is a society in which a minority rules the majority.
Now, of course, in a democracy the majority can use violence to suppress the minority. But that is in fact the bulwark of democracy: the majority using violence or the threat thereof to suppress royal families, warlords, etc. And while ideally the majority does not do this, oppressive rule by the majority is almost certainly preferable to any situation where the minority is in power.
