bhaji, i do exactly the same as you do and watch other dharmic channels, but what u mention should not be a suprise because whenever i turnover to the some muslim channel all i ever see is the people bigging islam up as the most superior faith in the world, and the christian channels (that i have wathced) are the worst, they proclaim other faiths to be the result of the devil to take people away from devotion to chritst and believe we non-christans go to hell.
cheap sikhs (if they were sikhs in the first place) are common- you see sikhs bowing their heads to idols, tombs, pakhandi babe and etc and i have actually been to some of these places and witnessed this. Anyone can buy these people to convert to there faith because they have no stable ground to stand on.
i was watching a english lecture on youtube some time ago by bhai nirmal singh where he makes an excellent point about sikhs converting to islam. He says that in order to reject something, you must have the understanding of what you are rejecting- if you did not know anything about sikhee in the first place, then how can you possibly be rejecting it, and thus be converting from sikhee to another faith. Its very ironic and does not add up to a logical conclusion.
