From what I understand what you mean, that in general Touhou sucks, I already know that the "cookie" thing exists and how cringey it is (it's like a poorly done lobotomy to the "franchise" if you ask me)
Not Touhou that sucks, just its fanbase, which is typical of any large fandom. It's also not really a very fair judgement, since we're judging based on the fucked up minority. The unpleasant members stand out the most, and there's going to be more of those the larger the sample size, but the majority of most fandoms are actually perfectly fine and normal.
Their point was that fans aren't better or worse depending on their country of origin. The Japanese fans have just as many controversies and bad apples as the western fans. You just don't hear about them because they happen in Japanese spaces, but if something happens in the English speaking side then of course you'll hear all about it.
Ibuki, 5 months pregnant: "Sensei! Look, look! My belly's gotten so big! It's a boy, so I hope he grows up strong and cool, just like you, Sensei!"
Sensei: "...Yeah..."
Sensei (thinking): (Yuuka: "Ibuki-chan is pregnant!? …This can't be!! Sensei, did you take advantage of Ibuki-chan!? That's so low. Stay away from me, you're disgusting." Noa: "…I'm sorry, Sensei. I'll be leaving early today. I'll finish the rest tomorrow… Excuse me." Momoi: "Midori!!! Midori!!! Don’t do anything rash!!! We don't even know if it's true yet!!!" Aris: "If a baby has been conceived, it means we have a new comrade." Momoi: "Aris, shut up!!!")
Sensei: "Ibuki, come over here."
Ibuki: "What is it, Sensei?"
Sensei: "…" (sound of something clicking)
Ibuki: "Is that... forceps? Did you borrow it from the Remedial Knights?"
Sensei: "I'm sorry." (sound of something piercing)
Ibuki: "Ah!!! It hurts!! Sensei!? Sensei!? What's going on?"
Sensei: "You can't be allowed to give birth."
Ibuki: "Blehh (sound of vomiting)... Sensei… Please, stop."
Sensei: "…Here it is." (pulls out the fetus's leg)
Ibuki: "Sensei… hic… What is that?"
Sensei: "It's… part of the baby."
Ibuki: "Hic… hic… Uwaaahhhh!"
Ibuki: "It hurts!! It hurts!! Please, stop!!!"
Sensei: "I'm sorry… I'm so sorry… (sound of removing the remaining parts)"
━━━━━━━━━Several minutes later…
Ibuki stares blankly at the ceiling.
Sensei: "I'm sorry… The Medical Emergency Club is on their way."
Ibuki: "Sensei's… baby… My baby… hic… I wanted to play together. I wanted to go to the park. I even wanted to teach them how to draw… hic… I wanted to show them to Makoto-senpai, and Iroha-senpai… My precious, precious… Ibuki's… sniff… baby."
Sensei: "…It seems like the Medical Emergency Club has arrived. Ibuki, stay calm. I'll explain the situation to Sena."
Sena: "Sensei! What happened? I heard Ibuki-san was injured and rushed over."
Sensei: "Oh, Ibuki stepped on a landmine at the park. As you can see, her internal organs are damaged. She needs immediate treatment."
Turns out that actually is the French flag she's holding, but it appears to be the version that's hung at the Arc de Triomphe, which has lateral stripes instead of vertical.
