It is an irony that in the world today, many are extremely intolerant towards those who do not buy in to their self-perceived concept of tolerance! "Look at human history, filled with intolerance. Now we are going to fix it. To hell with God and all that stuff. It has not worked until now." In effect, they take the high ground of demanding the abolition of evil without recognizing that they are not exempt. The Golden Rule applies in theory, but in practice, sheer hatred towards anyone they perceive as not on board is totally justifiable. Sounds strangely familiar - the trap of too many religionists!
Enter one universal God, Love, Principle, each one subject to this God - NO intercession, dogma or religion or person.
"One infinite God, good, unifies men and nations; constitutes the brotherhood of man; ends wars; fulfils the Scripture, "Love thy neighbor as thyself;" annihilates pagan and Christian idolatry, — whatever is wrong in social, civil, criminal, political, and religious codes; equalizes the sexes; annuls the curse on man, and leaves nothing that can sin, suffer, be punished or destroyed." (S&H)
On this basis only will genuine tolerance and inclusiveness be achieved - sort of like the law of gravity. It works. It's just the way it is.
