There's a difference between genuine representation, and artificial representation, though. Genuine representation CAN also include a character "looking like you" (though in reality just because I share a similar skin tone or ethnicity with a character doesn't mean they literally look like me at all), but that in itself is not the main basis for authenticity. It should, and has always, been down to how well-written a character is, what their expressed values and virtues are, their hobbies and interests, etc.
That's why I'm able to identify with so many characters who in fact may not "look like me", but embody aspects of who I am as an individual in one way or another. That includes characters of all colors (Steve Urkel, Goku, Blade, The Crow, Batman etc.), gender (Ripley, Linda Hamilton in T2, etc.), LGBT etc. That is authentic representation in my eyes.
I wish I could agree that places like ERA are irrelevant but when you have so many Western games media types proliferating there and dropping them by name in their own content, that in fact bolsters their presence online. Way too many gamin content creators name-drop ResetERA for rumors that don't even originate there 90% of the time, or gaming news in general, and that permeates with their audiences who will then...go to the forum and potentially get caught up in its BS.
So putting a spotlight on their horrendous takes every now and then is a good thing IMO.
