Yes, that’s fair - depends on how the definition of the survey is worded. So something like satanism wouldn’t be a religion to you? I get it confused with the church of Satan, but one or the other isn’t about the worship of Satan. My grasp of Buddhism is it’s about a belief system, one that believes following his example that leads to a better life/ inner peace, rather than straight worship, or asking him to use divine providence to make ones life better.
