I'm sure nobody here feels their own background disqualifies their own opinion.if someone feels that their demographics disqualifies their opinion, maybe it does but that's exclusively on them to decide, that wasn't my question; I simply asked to put context to these answers. I have no qualms putting my background and perspective out there because I'm aware enough to know my background informs my perspective.
The problem comes from the fact that OTHER people are going to use that to dismiss their opinions. Somebody will say what their background is and somebody else will reply with "That's nothing. You don't know what it's like to really be discriminated against."
