Among the heap of dumb things Hindutvavadis say and do, this is definitely among the dumbest thing. Most people ignore such people purely for sake of not hurting their feelings or insulting their religion.
Not only it is purely stupid and can easily backfire but also it is blatantly false. Why don’t they realise that they run the risk of someone insulting Indian religions, suppose if someone replies with this, “No my ancestors chose Islam because it was not false and repugnant like the religion they used to follow… after they understood truth of Islam they reverted and left the filth that their parents gave them as religion.” And this is putting it mildly, it could be much worse, they could say that “My ancestors were intelligent who recognised 2+2=4, but many of their companions and friends kept believing 2+2=22 and we have to deal with progeny of those who believed 2+2=22.”
What these people are saying is that Islam has nothing good in it, and whoever became Muslim became because he was enticed or forced into it. This is completely false, because as far as Muslims are concerned we think that our religion is full of goodness and those who do not die Muslims, their loss. The first Muslims were persecuted to death for being Muslims, Meccans were forcing them to renounce Islam and join the religion of their ancestors’, and to imagine that they did not see any goodness in Islam is stupid. For 1400 years the religion has its followers in millions and to claim it has no good in it is bordering insanity. The same argument stands true for Christianity.
Of the four Mongol Khanates, three of them became Muslims, where Kings adopted the religion of people they had conquered. Who forced the Mongol Kings to change their religion? Of course no one. Who is forcing people to change their religion today? I mean who forced A.R. Rehman, Michael Jackson or Cat Stevens to become a Muslim? Who could force Mohammed Ali or Mike Tyson to change their faith? Who forced Wayne Parnell, Frank Ribery and Sonny Bill to become Muslims? Just a few days ago Van Klaveren a leader of Europe’s most vitriolic Anti-Muslim, Anti-Islam party led by Geert Wilders party reverted to Islam. And he was not the first from Geert Wilders party to revert, another member Arnoud van Doorn had reverted to Islam few years ago. The fact is that people choose Islam out of their free will, nobody is forcing anyone.
