The pain and oppression he feels is real and it's caused by patriarchy And capitalism. Not the LGBTQ community. Other forces have validated those feelings but pointed to gay and trans and brown people as the cause. Rather than dunking on them with "are you even oppressed bro?" Like many others here are suggesting which they admit would never work because of course it wouldn't work who responds well to that, the best way to change someone's mind is to talk with them validate their feelings and struggles and fears and point out that it isn't minorities causing these issues but direct them to the real cause. I know it's hard to empathize with people who see you as the problem but it's the only way to actually change their mind and get them on the right path if that's what you actually want to have happen. If it isn't then go ahead and hit them with a "check your privilege shit lord" and go about your day knowing you just owned the patriarchy
