They have committed an insane amount of genocide in its history and did the same thing isis does now in destroying historical places. Not long ago it was found a few priests molesting young boys. Hollywood neither hates nor likes the Catholic church, they are just the easiest to write for when the script calls for something religious. Hollywood has often portrayed them as the ones saving the day from evil and when a script calls for it they are the bad guys. I'm not a religious person but I do live where mostly Mormons roam. I've seen far more agenda aginst them in TV and Hollywood due to so much ignorance about them. They don't have multiple wives. They are pretty normal everyday people.
I'm a Mormon myself and yes we do get a lot of hate, mainly because ignorance, but I got used to it.
I was technically Mormon as a kid but left on my own and came back briefly in my 20s for 3 years and left again. Just not for me as an agnostic. My mom is an active Mormon. I quite enjoy them as they are pretty genuine. I do sometimes go to the dinners and Ward stuff. It can be enjoyable. I've grown used to it as well.
