Well, let’s see if you belong. Answer a simple historical question.
Do you accept that Jesus was put to death for blasphemy, claiming equality with God? Even his enemies acknowledge the claim.
Why isn't the question "Are you an atheist?"
The report that Jesus said, "I and my Father are one" comes only in John 10:30, and is not reported as leading directly to his crucifixion.
Nor does the context here & elsewhere suggest Jesus meant anything other than you or I might mean in saying: "when you're talking to me, you're talking to my boss."
In fact, there are different schools of thought on exactly why Jesus was crucified, including one which emphasizes the Romans' political fears that Jews might raise up a new king -- hence the plaque saying "King of the Jews" on his cross, reported by all four gospel writers.
