When Baha'is can get along with those types of believers, and also atheists, then I'll be surprised and impressed. Then let's see how Baha'is get those on the far-left and far-right to get together. Then Communists and Capitalists and on and on.
The vast majority of Baha'i come from all walks of life, religious traditions and no faith. They have already brought down many barriers to become one people under One God. They have embraced change and are learning to work together by embracing all people of all Faiths in the same light.
There are many barriers and walls that need to fall for that to become a global realisation CG. People have their own choices when they are faced with a proposal of change.
It is good to ponder this passage. Isaiah 45:7 "I form the light, and create darkness: I make peace, and create evil: I the Lord do all these things"
The Word given by God is the Light, our neglect creates the darkness that surrounds humanity, the Word is Peace, our neglect of it is the evil we bring upon ourselves.
A Baha'i shares the Word of God given by Baha'u'llah, and as per Isaiah 45:7, that Word unfolds as light, or as darkness, correspondingly to our willingness to submit unto God.
God allows all our mistakes. Baha'u'llah advised the few people that intended to take the Shah's life for execution of the Bab, against doing such a crime, yet they did not choose that advice, Baha'u'llah did not change their choice and the result was horrendous suffering that still unfolds in Iran today.
We are responsible for our own choices, we have no control how another responds to the Challenges given by Baha'u'llah, but to learn wisdom ourselves.
