When people refer to themselves as TamBram, they are just referring to their heritage.

If you are offend by them carrying their tradition or culture that they have inherited for 100s of generation.

How would you then think of Indians named John or Mohamed? You know that, these political religions spread almost exclusively through violence and colonisation.

India is a strange country where it is ok to engage in hate against indigenous people/culture, yet political incorrect to even speak of the violent history of Christianity or Islam.

You are perhaps engaging in the same kind of hate the Nazis spread of the jews.
