One thing NOT in common...the LDS probably won’t issue a decree to have you slain or beheaded.
When I was working for Utah Power and Light in Utah I asked a RM and Mormon in good standing if his Bishop told him to kill me would he do it.
He said that is a hypothetical question and then said yes.
That was when I decided to move out of Utah.
Up until fairly recently, by historical standards, the Catholic Church had no problem with burning people at the stake, consfiscating their property without trial, torturing people until they confesed to 'heresy', etc.
It'd be interesting to tally up whether islam or Catholocism has the higher body count over the last 1500 years or so.
The LDS were very aggressive, and the reason Americans hated and feared them so much is that they came in and literally took over these isolated frontier towns. Mad Mo did exactly the same.
While islam separates your head from your body, mormonISM separates your soul from God Almighty.
