Fringe Christian groups are another matter. They are simply going to create friction where very little existed for a very long time. The Christians of Mangalore were an integral part of the city & its culture. These nutcases with their aggressive proselytising are causing a breakup of that cultural harmony. Unfortunately, there is very little that can be done about them too. The law allows them a certain amount of freedom & very little can be done, legally at least. ( My own views on proselytising are slightly strong - I believe that anyone claiming his God is superior - for the purpose of conversion or that he can grant someone a place in Heaven should be immediately arrested under Sec.420 for cheating unless he can prove his claims. That in my opinion would do the trick)
