The 48-year-old Bollywood star said he is better off doing his bit for society by being an entertainer and a creative person but that does not mean he sees himself as a social activist or would join politics.
"I have a big contribution to make from where I am. It is a big responsibility. Also, I don't feel I belong in the field of politics. I won't be that effective there, I won't be able to function there," he said during an interaction with women journalists at IWPC on the eve of Women's Day.
"You don't have to be in politics to do social good. I believe I can make a huge contribution from where I am. This is why I would not join politics," he said.
The actor, who once supported the Anna Hazare movement, said he does not support any individual party though he agrees with Arvind Kejriwal-led Aam Aadmi Party's concept of swaraj.
"I agree with the concept of swaraj. Most political parties say we will govern you well but they (AAP) are saying that you will have to be a part of the ruling process. But I will not rush with my support as they have yet to be tested. I don't want to have knee jerk reaction about it."
When asked about his favourite political party, Aamir said it would be unfair on his part to influence the electoral process anyway.
"It would not be right to name a political party... I don't want to influence the process anyway. I think we won't be able to change anything if we think someone else will come and rescue us. The messiah is not an outsider, it is inside us," he said.
"More or less all the political parties are similar. I don't think if any one party came with majority, it would change anything."
When asked about his opinion on the way Raj Thackeray's party Maharashtra Navnirman Sena treats people from North India, Aamir said it was wrong for any political party to use muscle power.
"Any political party which uses power and muscle in the country is wrong. Earlier during the struggle for independence, Gandhiji would say people to boycott something and they would do it voluntarily but if I use force to stop people from leaving their houses. They burn buses, use violence. It just indicates hooliganism. You are just a goon. It's not got any ground support."
