Look, Baha'is do not ask believers of others faiths to abandon their faith anymore than many Christians do it, often even less so.So Bahai apparently accepts Christ, accepts Christianity and tells Christians to leave their churches to follow Bahai? It accepts Judaism but tells Jews to leave their synagogues? In effect to turn their backs on everything that they are, all their heritage, and walk away?
And that is supposed to be acceptance leading to world peace?
Yeah, no. Massive acceptance fail.
When I meet a Jew I accept who he or she is, and I make no attempt whatever to persuade them to leave the synagogue. I might ask permission to visit the synagogue with them but I would not want them to leave it. Acceptance means valuing the person as they are, not as they might be if only they were different.
I can't speak for all Baha'is, of course, so this is just my view:
To my knowledge, active or aggressive prozelytization is even forbidden in the Baha'i scriptures -- unlike teaching the faith to those who are interested and want to listen, or ask for it. We just offer our faith, but don't force or push anyone to join it.
I've met Christians who hate Jews, who quoted verses from John claiming Jesus said "Jews actually worship the devil", and justified their hatred against Jews by claiming "they killed Jesus". It's easy to find Muslims who hate Jews for various reasons, and they too are quick quoting some verse from Quran. I believe they are misinterpreting these verses.
But the Baha'i scriptures explicitly command us to meet believers of other religions with utmost politeness, friendship and peace, and fanaticism and religious prejudice are explicitly condemned. Now of course we're fallible as all other humans too and don't always meet our own standards, but it's next to impossible to twist our scripture to find a justification for enmity towards people of a different faith.
Sometimes, I have Jehova's Witnesses over and we have great spiritual talks, but I don't attempt to convert them. When I disagree, I do so in a friendly manner. When they ask, I gladly offer explanations about my faith to the best of my knowledge. Nice chats and talks and great respect for each other.
It's totally okay when they don't feel interested in the Baha'i faith, or are not convinced. But if they do, if they learn about Baha'u'llah and are convinced He is a manifestation of God at some point -- sure, then it wouldn't make sense if they stayed with their old church or faith which rejects this claim. But nobody is pushing them. It's entirely their decision. I don't retract my hospitality towards them when they don't.
