I reject your claim that Mormon was ever or is an epithet, and I reject that this is an explanation church leadership has ever attempted to use before RMN (and I’ve never heard his presidency trying to pass it off as such). Please present authoritative evidence of your claims (and not just rhetoric from apologists like FAIR, which do not have actual church endorsement).
I understand that leaving the Church is an emotional experience and leaves most people very bitter, but do try to moderate your hatred.
