The لا shirt was a t-shirt with the Arabic word لا ("no") in large type across the wearer's body. Wearing it loudly rejects fascism and islamophobia by making the Arabic language more visible in public spaces and by literally saying "no". It was available on Teespring in black and white and all profits went to the ACLU.
The description read "لا to fascism, لا to racism, لا to homophobia, لا to bigotry." Soon after its launch Teespring killed the project without recourse or explanation. The best theory is that their automated moderation tools are likely hard-coded for English and filtered out the Arabic text, causing the description to read "to fascism, to racism, to homophobia, to bigotry" -- a celebration of the things the project rejects, and a violation of their terms and services.
