Why not have a law that allow all Shias to enter sunni mosques, all blacks to enter churches of whites, all catholics to enter protestant churches, all dalit christians to enter "Brahmin" churches ....
In fact make a law that makes it legal for infidels and pagans to enter heaven of Islam and Christianity.
Why pagans and infidels are denied entry into heavens of Muslim and Christian faiths? They have 100 percent reservation only in their hell.
