Syncretism is the act of integrating new cultural ideas into the ones that already exist.
It’s very common in the evolution of religious practice. Instead of ‘this’ or ‘that’, the answer might be ‘both’.
Sometimes, we’re so eager to fight off a new idea (to protect an old one) that we miss an opportunity to imagine how our world could go forward instead.
It’s much easier to be unequivocal. It’s also not that productive.
It’s possible to be in favor of something without being against something else.
