This kind of rhetoric rises from what I’ve called the Authoritarian Left, which is an immensely detrimental wing. It’s a group where there is no nuance.

There is no nuance that you are aware of that the trans people that are calling for a ban of HP haven't already thought of. It's their lived experience after all. They know so many more nuances to this, or any other trans issue than you or I do. I don't know how much time you spend in the discussions of the so-called "👻Authoritarian👻 Left" but I've found them to be immensely nuanced. Cis people don't get a contradictory opinion on what harms trans people and what doesn't, simple as.

You say that if a trans person says it’s hurting them I should stop doing it. OK, but what if a republican says it? Now suddenly I should ignore them?

It's not just one trans person though is it? It's a pretty widely held opinion in the trans community afaict. That bit about some hypothetical republican didn't make sense to me, no idea what you're trying to say here.

I love trans people, and I actively fight for them and their rights.

Maybe a bit more listening is due? A good start would be Trans Liberation: Beyond Pink or Blue.

I’m a durable ally. I’ll stick with it when it’s not cool or trendy, or when it comes at a cost.

Except when that cost is giving up Hahree Pawttah apparently.

To loop all the way back to the premise - if talking about Harry Potter at all hurts Trans people, then this post hurts trans people.

Talk about "no nuance", obviously this post isn't suggesting that the mere mentioning of the name is causing trans people worldwide psychic pain. But not purging Harry Potter from your life, giving space to a franchise that is used to hunt trans people is actively harmful. Wouldn't you be suspicious of someone who is still a huge "The apprentice" fan? Or a huge "Tesla" fan (" Oh I'm not buying their cars, but I still admire them!!")? Similar sentiments apply here.

You have to allow more than one idea in your head at the same time. If you’re making the rule “talking about Harry Potter in any way, at any time, makes you an active enemy of the trans movement”, then that’s not a place I want to be associated with.

More generalizations from the nuance-haver, I think it's addressed above but just to reiterate, its about purging a franchise from your life that is having a toxic effect on the world.

If you want advice - focus on how JK Rowling is harming people.

I'll take my advice on fighting for the trans cause from trans people thanks.

This authoritarian left wing of democrats is what got Trump elected.

Source? I don't believe that the democrats even have a left wing, much less an 👻authoritarian👻 one, much much less one that is powerful enough to have decisive swing in the presidential election.

the real trick is not scolding people into adherence

I'm gonna keep telling people that are platforming fascists that they are platforming fascists. If they continue to do it, I can then know where they stand.
