Christians what do you think of the Baha'i religion?

Is it a false religion?
How about their prophet?
Is it wronger than Islam?

They are nice people who are wrong.

If it leads them to god, it is right.

they're quite annoying and (i should say the ones i know, i know it's not fair to judge them all) are condescending and think they know everything and think they're so "tolerant" and "mature"

I have no idea... but your grammar is "wronger" than a lot of things.
