(Slight tangent, but others have posted similar things.)
This is probably my least favorite part of any fandom/nerd-community.
I love D&D. I love a ton of fantasy and sci-fi books, shows/movies, and video games. I love consuming sci-fi and fantasy media. I love listening to music, too. There are some celebrities that I think are genuinely funny and seem nice.
I just don't get why some people feel the need to idolize them and put them on a pedestal. They're human. They make mistakes just like the rest of us. A lot of them make worse mistakes than we do. There are some creators that were absolutely garbage people, but created good things.
The "creator worship" that a lot of nerd communities and fandoms participate in is . . . baffling to me, to say the least. It's legitimately harmful to treat creators this way, even the "good ones". The ones that are legimitately decent/good people don't deserve that kind of worship, and it cannot be good for their mental health to feel that they need to live up to their fans' unrealistic expectations/viewpoint of them. It's extremely harmful when this happens with awful creators, especially those that are still alive. Celebrity worship of dead people isn't good, but doing it to alive people that are garbage people is one of the worst common practices in the modern world, IMO.
Whether it be Joss Whedon, JK Rowling, Michael Jackson, Gary Gygax, David Bowie on the bad side of things, or others that seem to be good people . . . they should not be idolized. It's bad for everyone.
Side Note: I was raised in a church where I was taught to basically worship certain alive individuals as if they weren't human people, but instead as if they were better than all of the rest of us, and to do exactly as they told us 100% of the time, even if they were wrong. Most of my family and I have since left this church (cult), but my family and I are still dealing with the fallout of this type of indoctrination, and it's extremely harmful in many ways.
No one should idolize anyone. We're all humans, none of us are gods, and it's extremely harmful to treat people as if they are "above humans". (I actually think that a major part of maturity is learning to treat others as people and not as perfect. We see our parents as perfect growing up, and a large part of the teenage years is learning that this isn't true. Those that can't learn this are a major part of what makes certain adults immature.)
