I can't imagine why people might feel that the opinions of white men might be well respresented already.
The world does not suffer for a lack of opinions on anything from white people -- it's fair to say such opinions are even overrepresented in the world of available writing.
If people already well-represented care about diversity, they should help some of the not-well-represented speak up.
Weird statement, either way.
If I was born with green feet and you were born with pink ones, perhaps my opinions should hold the same weight as the guy born with pink feet. Just because you were born with pink feet doesn't make you any more or less special than me.
No one said that. Feeling insecure?
I'm just pointing out that you saying that because someone is from the majority then their opinion counts less is flawed.
