Your whole arguement which is pointless anyway is based on bigotry. Nationalism firstly is not limited to any one religion especially in our country, if it is not related to islam then it is not realted to hinduism or hindus either- there was nothing like hinduism in the medieval era, there were several sects cults dieties worshipped in different parts and you are grossly incorrect in considering it a monotheistc religion like islam, it was only during the national struggle that this tag name of hindu was adopted....so if u call yourself a hindu cus you dont even know where you or this identity tag that you carry comes from.
One thing you and bigots like u who think this way should remember is that you could be one of the descendants of ghori,ghazni taimur or even mongols and afghans...they obviously intermingled freely with the indian population then. So save your frustrations and do everyone a favour by not spreading your hate...especially to your children, i hope people like u dont have any.
