Sure, I get that. But it's been the rule to never show blacks in contexts where we know they existed, and were even common. So a little balance doesn't seem unreasonable.
Lying is still lying, even if you feel that the lie accomplishes some political agenda that you happen to believe in. In this case, if you say that this is a typical family when it is not, then the fact that you lied for what you think is a nobler purpose doesn't make this OK.
