Yoga is based on Hinduism and has practices like astral projection, OBEs, chanting, and the stretches and positions can be used to honor the gods. (small g) Would you call them intollerant if they banned a Celtic winter solstice event?

Yoga from a Christian Perspective Resources - Christians Practicing Yoga
I never heard of anyone talking about or practicing yoga during my first 20 years of life growing up in India as a Hindu. And my family was pretty devout religious, which I am not. My wife and kids are Christians. Only after arriving in US at age 21 I heard of all these yoga classes going on everywhere. I never have attended a single yoga session in my life. So I do not know first hand anything about it. But my impression is it has more to do with physical exercises than religious rituals. If indeed they were pushing Hindu religiosity during yoga sessions, I do not think it would be so popular here.
in the same way martial arts in many cases is based on Chinese philosophy.
I think we need to separate out the Hindu religious part from the exercise, just as how many of us have done so for martial arts
