the father kept his faith in sikhi and in the end they got the treatement.
i see it this way. we have shri harimandir sahib, what do christians have. i have no fear because there will always be those gurmukhs that will never betray there religion. then there are the sharabdharis (alcohol devotees) who won't follow the path of god if it is jesus, muhommad, ram, or guru ji. they just need a bottle.
a really knowledgeable sikh was telling me about true parchar. the most effective parchar doesn't come from any baba or keertani but from the sangat you are around. if you love sikhi, then try to teach to others around you. this is one of the biggest weaknesses in sikhi right now. people stay in bad sangat and let them influence them in the wrong way. that is why so many sikhs in punjab are giving up sikhi in punjab. no baba or sant can do the parchar that i think will save sikhi. in not saying that you shouldn't stay in bad sangat. i say you should stay in bad sangat and influence them about sikhi instead of letting them mess with your mind.
