Here’s the news: My invisible friend is better than your invisible friend. Therefore I cannot allow you people to celebrate your non-religious family festival in peace. I must bring a pig head on a stick and a megaphone to preach that your religion is false. Such is Jesus’s message of love.
If you click through to the description text on youtube, you’ll see that the Christian missionaries express surprise that their message of love was greeted with the throwing of bottles and eggs. Because Jesus taught that passive aggressiveness is the way to spiritual truth and love.
