There is nothing to prevent anybody; you are free.... For instance, when I was there on holiday, I was staying with my wife's sister. There were Christian folk who came, knocked on the door, and would chat or hand out literature. There's no problem with that, but these allurements given to the poor, exploiting their poverty and then asking them to go and publicly smash their idols, their religious idols, that is what is causing the problem.
