Don’t know much about real Mormonism do you?
The basic heretical teachings (Christ was created, earned his godhood, Jesus is the spirit brother of Lucifer, salvation by works) are teachings ALL attending (active) Mormons know and believe. And it is the basic teachings that make them not Christians at all.
The reason the LDS get ‘basic’ Christian questions ‘right’ is because they have different meanings for words Christians use. They intentionally do this, knowing Christians mean different things to ‘sound’ Christian. That is deceptive.

As a child we moved alot for my fathers job. The differences of what, how and “requirements” varied geographically. Its very different in different places. I remember in my teens a woman getting excommunicated for her unrepentant sins (living with another man after her husband left her), while in a different location 2 unmarried cohabitators being included and their children blessed at birth in the sanctuary. Very different actions for essentially the same sins.
So yes I know it very well and as a kid I always wanted answers. If some said the sky was blue, I would want them to prove it otherwise it was whatever color they hated most ;). I was just that way. Most Mormons don't know what the church in Salt Lake believes. The are/were more locally flavored. Combine that with the fact that a majority of people are stupid and lazy, they just don't know many of the off nominal BS of Mormonism and are Christians that just don't know better.
JMHO. Your experiences may lead you to a different conclusion. Either way, I find most Mormons to be good, straight shooters. Unlike them damn Methodists - now there are some wacked out cultish people. Stay on your toes around them.
