How do i revoke my membership from the church of jesus christ of latter daYsaints

Stop going. If anyone asks tell them you don't believe in the Mormon way anymore. You don't have to justify it just walk away. For several years before the pandemic 7th day Adventist would visit and talk to Vickie always trying to convince her that Jehovah was the Lords name. She would bluntly disagree yet they continued to come. I asked why don't you tell them to stop coming. She said they are nice ladies and it's fun confronting their challenge.
So if you get hassled and can't get away from the conversation do what she did and find an answer to the challenge that makes it fun for you rather then stress out.
