This is not at all surprising to hear, mainly because I've heard it all before. Of course you are entitled to your opinion. But I maintain my stance. Yoga came from Hinduism, is a central Hindu practise, and to this day literally reeks of Hinduism. It has Hinduism written all over it. But over the years many people, mainly because they couldn't reconcile the two beliefs
1) Hindusim is bad, of the devil, un-Abrahamic.
2) But the practises have benefit.
Those two beliefs just didn't make sense, so they tried to separate them, pretend there was no connection. That's all fine too. It is a free world after all. This sort of thing happens all the time. For awhile American car companies bought Japanese cars en masse, and gave them an American name, so they'd be American and Americans then bought them. "I sure won't buy one of those Jap Toyotas, but the Chevy Nova is so much better." So people do get fooled by the label.
