I am just saying he should only do what he is supposed to and stay away from political activities
Are you going to decided what he is "suppose to do and suppose to say" ?
He is not asking people to vote for BJP because they are Jains. He is advocating for a Vegetarian society.
CONgress is free to promote a Vegetarian society and seek votes on that basis.
BJP is not a Jain party.
In fact BJP is supporting abolition of Triple Talaq, so shouldn't women organization, especially muslim women org. advocate voting for BJP ?
