what I'm trying to point out is that simply putting on the label that you are whatever you claim you are does not make you whatever you claim you are. for example, the essence of Christianity is that you believe Jesus is God and he rose from the dead to pay for the world's sins, every single big religion rejetcs that, including Islam including Judaism, including buddhism and hinduism, so when I hear a person claiming to be both buddhist and Christian I know that they're neither
They clearly referred that they aren't a "very religious person" and having two religion is common in diverse cultural countries
