Right, you left The Church and joined a grouping outside The Church. Whether that grouping is a cult or not is your issue or it may depend on the level of brainwashing. The Church does not do brainwashing and is not a cult, rather the repository of The Faith in Christ.
That’s a laugher if ever I saw one.
The “catholic” “church” is, perhaps the world’s largest cult - spread through brainwashing that is cultural in nature. Someday, kid, you’ll learn the true nature of your “church” - and then you’ll understand.
