What to do with such kind of people?

So there was a reel where Tamil Nadu people and Karnataka people were vandalising Indian railways and marking black on Hindi written on any place. Then some people commented against it so as 1, and here we are seeing their real faces. Posted some ss, there were literally so many of comments filled with hatred and disgusted comments on Hindu re**on and gods and demanding separate nation. Ik this was a funny one but this was serious and I feel we should take some actions against these people. What u guys say? Or I am just feeling a little too much?
