should be fine since nothing happened

Sometimes I wonder if there's a parallel community of terminally online Chinese power posters who spam "Americans don't know about 9/11" all day.

I imagine it would be about the fake evidence used as justification to invade Iraq. 9/11 isn't anything remotely comparable.
(And of course, the US is not the same, as you can talk about the Bush's perjury all day long and not get arrested. Although it is similar in that you can be brown and sent into a concentration camp.)
- you can talk about the Bush’s perjury all day long and not get arrested
  You can talk shit on the internet to nobody in particular and not get arrested. As soon as you start getting national attention, the hammer drops.
  John Kiriakou, Thomas Tamm, Lawrence Wilkerson, Teresa Chambers, and Chelsea Manning were all subject to investigation, firing, and some range of prosecution with varying results for efforts they made to expose Bush's administrative criminality.
Bro we celebrate 9/11 here in America - it made us the world victim for like 20 years. Verb, noun, 9/11. I BBQ every year. I don't think our tickle fee fees are gonna be too hurt by these chinese posters. 9/11 truthers love this.
- It killed almost 1/400 Americans as the biggest recent disaster, covid.
If they hop the wall they'll see our 9/11 jokes, so no

I don't think "T.S." means anything to most chinese...

"TS" is far from "Tian An Men Guang Chang".

It is not even sure if authorities notice it...

Tiananmen Square? This would be dead obvious to Hong Kongers. Hell, even just '1989' is enough.
You don't see people wear shirts that openly criticize the CCP these days. Not after all the arbitrary arrests where even wearing plain black clothing was enough to incriminate you.
I don't recommend going to Hong Kong anymore. It's a husk of its former self. The streets are far emptier, and every other storefront is closed because people and business have packed up and left in droves. If you do, certainly don't wear this shirt there.
- It’s really sad hearing about all of the protests there over the years since it was returned to China. And how they basically did nothing, despite so much effort. It doesn’t make me hopeful for what is going on in the US right now.
- I spent some time living in HK before the mess and loved it, despite not being a big city fan. The other day I crossed a family from there here in Europe and the dad told me they fled because of it. I'm kinda curious to go just to see the changes for myself.

It would be odd if you were a T.S. Elliot fan

You reminded me of this gem:
It was just suppose to be a one-off joke, but the guy ended up having to print that shirt and sell it due to overwhelming demand.

TaiShan 1989? Nothing happened there.

Edit: /s just in case.
