I work with a lot of brown and asian guys. I tell them this: You can't change what you can't change. Can you change your accent? Yes, with classes and study perhaps. Can you change your race? No.
So rather than focusing on changing someone's stereotypes, play into them. Make fun of yourself. What are stereotypes?
Indian Guys: They have bad game, smell bad, like to drive orange sports cars, are corny? Solution... learn game, get a Tesla, wear deodorant. And then joke about all of that when you're with girls. "Yes, yes, I know I should drive an orange Camaro and smell like Curry, sorry to disappoint. That's my Tuesday look."
Asian (Chinese, Korean, etc): Small dick, good with math, nerdy, shy. Solution: Small dick you can't really fix easily... but you can be great with your fingers and tongue. Have game, be social, be confident, and outgoing. "Yeah, I know... you're wondering... how small is his dick? And can he do my math homework? The answer is... Yes."
Game wasn't made for tall, rich, handsome white guys. It was made for guys who are underdogs, who struggle so that we can compete with them.
And realize... you can't read minds. Every newbie thinks he's a mind reader. You're just projecting your insecurity if you're out there wondering about unconscious bias. Waste of energy. Focus on what works... being positive, social, and bringing in leads.
