Will it take many years for other religions to find mainstream acceptance in the US?
The term "other religions" is ambiguous. In the US and most of
the western world there are Christians, Jews, Moslems, Mormons,
Buddhists, Hindus, Wiccans, Native religions, Voodoo, Spiritualism,
Scientology and many others. References to aspects of these
religions and their beliefs are easily understood by most literate
people. Practices of the religions (meditation, yoga, statues of
the founders) are common even when divorced from the actual
religious beliefs. All of these factors would class as mainstream
acceptance to most observers.
