Do you feel he got scared when I said I am a Bengali?

So on this site in one of my previous post, I shared the video of the Rolls Royce Cullinan and a Maybach S680 which I saw in our city Bangalore in India. I am a car enthusiast so I get excited seeing these cars. But this user on here who is also an Indian downplayed my excitement and enthusiasm saying what's so special in it and that there are millions of such cars in India. He is definitely exaggerating it as there definitely aren't millions of Rolls Royce in India. They are super super rare. So I replied asking whether he is even an Indian and also said how rare these cars are here and even said him that people like him can only dismiss others who are enjoying a hobby. That made him angry and he switched to Hindi calling me a Chutiya, bhenchod and Madarchod which are very abusive swear words in Hindi. He also said me to go to Chandigarh, Ludhiana and Delhi to see the cars and told me to grow up and eventually called me a "Saala Mallu" and Mallu is a slang word for Malayali people from the southern Indian state of Kerala.

Idk why he assumed I am a Malayali person just because I live in Bangalore which is a South Indian city even though I am a Bengali from West Bengal state of India. Yeah I didn't mention in the post that I am Bengali so he probably assumed I am a South Indian. I also replied in Hindi saying that I am not a mallu and I am a Bengali and that I am 25 so I am already grown and also called him an idiot and a Saala too. After that he didn't reply anything. Do you feel he stopped replying because he thought I was a Malayali person but turned out to be a Bengali?
