She doesn't hate trans people or are against their lifestyle. She just has a different opinion than the mainstream so they'll try to cancel her.

I would argue against it. In my opinion stories were always out of the control of the author once released. If you and the author disagree on what can be seen in the stories, then the author hasn't the higher authority anymore. The author can make opinions clear from the outright, but probably many intentions are more hidden and everyone is free to interpret them. To bring it a bit away from Harry Potter, I would bring up Shakespeare. A modern reader of Shakespeare (or visitor to a play) for sure interprets things differently from what Shakespeare thought about it. That doesn't mean the modern reader is wrong. It just means there is no 'right' interpretation of a workand more importantly nobody owns the right interpretation.

So if you see Harry Potter books in a way and feel now Rownling maybe sees things differently, than your interpretation is still right - for you.

Dude... look at how much people on this site get upset about things like people disagreeing with them about which video game machine they like best, and how defensive and hostile they can become towards people who like a different video game machine the best.  Or how people literally sometimes stab each other because someone dislikes their favorite sports teams.

People care very deeply when someone attacks something that is part of their identity, even a very trivial part. It's not hard to understand why people may get more upset about someone attacking (in their view at least) something that is a core part of their identity.

While I mostly agree with your post, one thing I want to add: nobody  should shut up with their opinion. Everyone should be open to arguments to the contrary, but don't talking about your opinions doesn't make them go away. So everyone should always feel free to offer their own opinions, but should be prepared to get counter-arguments.

But shutting up only means some people dominate the public discourse while others still have differing opinions - only shutting up. This allows to produce societal divide. Also, simply speaking, if people don't offer their opinion that the moon is made of cheese you never get the idea that you should disprove that notion.

I can certainly understand being displeased by what an author says, but that doesn't really change the story. Be it people that became pissed when she revealed that Dumbledore was gay (certainly there is plenty of hints in the book), or people that get sad that she isn't an advocate for trans people that doesn't change the book.

Actually the interpretation of the book will change each time you read because you have changed as well. But there is a reason to not take opinion of others and even more of celebrities in account, because the only opinion that matters is yourself and at most the ones close that love you.

I understand it, and agree with you. And would you deny that people that act to this extreme doesn't need professional help to deal with their issues and improve in life?

A central pillar of that "different opinion" regards what rights trans individuals should or should not have, coupled with a lot of stuff that sounds like the same bigoted dog-whistles that have been blown by those standing in the way of trans rights. It isn't just the opinion that upsets people, it is the effect of this opinion and the actions of people who share these opinions.

Sometimes letting people speak is the only way to know you should keep the distance from.

Not sure what is the consensus, but I have seem considering woman with penis and without. Myself I consider transgender when the genitalia was operated. But there are gender fluids and other stuff.

Even after operation there would still be a very high portion that wouldn't go out with the trans because we are still based on biological need of procreation, so the impossibility of generating an off-spring would make the wish to go out null.

She just has a different opinion on what sex is and what makes a woman. She's never advocated for stripping trans rights or anything of that sort. Im not saying i agree eith her or anything cause honestly I dont cate that much but its its something I always see on Twitter. People have a different opinion thats not necessarily hateful and everyone tries to cancel them because its not what tbe mainstream sees as the proper opinion.
