Here's my two cents, if anyone cares. I generally agree with a lot of you, some more than others. The way I see it, I understand that as a principle, having more diverse stories out there is obviously a positive thing. Who wants to endlessly see the same thing represented over an over? But at the same time, I understand how the word has taken a kind of sour meaning of late, where it's more often than not become a buzzword to represent a certain kind of progressive group-think.
This is further enforced when people see companies like Marvel and DC changing every second established character into some flavour of minority, they see it for what it really is, pandering. It's pure tokenism. Even Stan Lee thinks it's a step in the wrong direction, and ask the most pertinent question of all, if you want more minority characters, why not just make new ones?
Conversely, that's what I love about the indie comic scene. Here, creators aren't yelling from the sidelines at creators, demanding that others include more 'x' minorities in their stories, no, they're out here on the front line, creating for themselves, telling the stories they want to tell, with the kinds of characters they want to see. It's how it should be.
But to answer the OP's original question, I have to agree with nocuddletime. What we need more of is diversity of thought and opinions. If for one would like to see more comics where the protagonist holds is a worldview that's diametrically opposed to what's considered 'acceptable'.
