Kumail literally had a stand up bit when he was much less well known about being called "Kumar" and how he dreams of the day that he is the goto point of reference that racists use to stereotype other brown people and himself. So Kal should proud of that, at least.

Also, I work with a lot of Middle Eastern and Indian people with a wide variety of names. It is weird that these three celebrities talking about being mistaken for each other all have names starting with K, containing an A, and ending with L. Kumail, Kunal, and Kal. Maybe it's not so much about them being mistaken for each other but switching similar names around, like white guys called Kayden, Brayden, and Layden.
