In workplace I have seen this non TN people support each other a lot but Tamilian will never support other Tamilian to come up in life . This I have experienced in real life too . Somewhere we lack ina ottrumai . Other states people support their people and stick together.
You are correct... Even I have faced it a lot at my working place... Whenever there is any trouble, other race people will come for my rescue than our own people... 'Rythm' movie'le Arjun Tamil nandu kathai solluvarule, athe mathiri... No offense, guys... Not everyone but mostly are like that...
