Ah fuck it. I'll just put it in the most blunt language possible.
The Harry Potter franchise is a money funnel that sends wealth and resources to a fascist who wants people like me to suffer and perish.
If you consume products of that franchise, you are sending money to someone who wants me dead and who uses her wealth to accomplish that end.
That's it. That's the bottom line.
If you can live with that, well, that's a fucking problem.
