If the Baha'i Faith is true, people should be interested in finding that out for themselves.
Well that's almost trivially true, since it would true of all beliefs, and all religions. Of course what religious apologists always fail to acknowledge, is that one would need thousands if lifetimes to properly examine them all, so obviously they are applying this rationale only to the one they believe.
nobody can muck up a message from God.
You might want to consider what that means for the fallible nature of most religious texts, purported to be from a deity.
It is and has always been the responsibility of anyone who wants to know if the Baha'i Faith is true to determine that for themselves.
Nonsense, the person making the claim carries the burden of proof, and again you can't possibly have examined all religions properly, no one could even if they dedicated their entire life to it, so you don't apply your own criteria to thousands of deities and religions. And of course, like all theists, you can't demonstrate any objective difference between yours and the rest.
The Baha'is are only responsible for proclaiming that Baha'u'llah has come and answering questions about the Baha'i Faith if people have any questions.
Just the one, same as I ask anyone making any claim, what objective evidence can you demonstrate for any deity? So far you've not offered anything beyond subjective anecdotal evidence, same as all the rest really.
