It is a stupid thing to say. Though its actually quite a common mindset. 'You're a male, you dont understand feminism' 'you're straight, you don't understand lgbt-discrimination' 'you're wealthy, you dont understand being broke' 'you're poor, you dont understand taxes' etc etc.

I think a lot of people who are emotionally invested in subjects are too ready to disregard an opinion of others if they know they don't share that same emotional attachment.
