Also, as a straight, white person myself, I understand that there are some discussions where my opinions are irrelevant and unwanted because I simply haven't experienced what others have and am unable to understand and empathize as intimately. Excluding my opinion isn't a slight against free thinking, it's a shortcut because I have nothing to contribute. Or in other words, outside perspectives are never useful? All the advice about having papers / presentations proofread by people not involved, about looking to outside sources to check if you're stuck in a rut, about the value of diversity of backgrounds and opinions, is all bullshit and worse than useless?
