Hi ARVHK, welcome to FlyerTalk!
Everyone's perception is different, and there is sometimes a disconnect between action and intention. Racism is indeed strong accusation, but I wasn't there, and I'm not here to assess that claim.
I guess a question back would be...what are you hoping to accomplish or receive? Is it an apology from CX? A more formal one from the ISM? Or is it compensation of some sort? I think knowing your goal in this might be helpful in finding the next step, should there be any.
