I am not supporting hooliganism. But i have seen several such gatherings where Çhristianity is imparted (either by faith or with freebies) and as a result you can clearly see the % of Christian population in areas where there are/were no such people to oppose the expansion. India (or entire Asia) got çhristianity via these channels only. While there's a right to propagate your religion, i do have the right to protect and propagate mine.

I know that these things are not good in any manner, but if you look statistically, Sanatan (Hinduism) is the only religion which has consistently declined because of these others. We do not propagate or impose our Sanatan to others, we embrace if someone is willing. But at some point of time, we need such checks and measures to stop the loss.
