Input: I work as a lifeguard at a private community centre. We had a regular come in the evenings and we would often talk about hockey and just sports in general. The community centre is mostly used by middle aged to retired Caucasian people. 

One day we were discussing Superstars like McDavid,Matthews, Crosby, etc. he was saying how they were probably scouted as a young kid and how they're fantastic. Then he said "just like how you would have probably been scouted for soccer(points at co-worker) and you at computer games(points at me)" While he was pointing at me he was laughing as he said it. He then jumped into the pool without letting me respond. 

I felt very offended that he would assume I played computer games and that I would be scouted for them. I called him out and said I don't like how he said that I would be good at video games because I'm Chinese. He got defensive and questioned why I would think that saying that I am young and assumed I played them. However, my coworker who was similar aged yet different ethnically would not get scouted for computer games?

From then on, he doesn't really talk to me anymore, and mostly just talks to the other lifeguard. In my opinion, it felt like he was associating being Chinese with being good at computer games. 

for context, I am a american born Chinese person, and he was a retired Caucasian man, and my co-worker was a bigger caucasian male. 

Am I overreacting and am I the asshole?

assuming someone was being racist to me
