My architect brother managed the renovation of the Noguchi Museum, so this is personal.

Since we both know that a keffiyeh is an Arab swastika advocating genocide to make "Palestine free (of 7.3m Jews) from the river to the sea", it should be as banned at a workplace as a swastika or a Soviet flag in eastern Europe.

Would you allow a rising sun flag to be displayed in a South Korean workplace whose employees include survivors of Japanese sex slavery in 1948? Don't think so.

I had a student at Riga Business School whose grandma was deported twice to Siberia, once at the age of 8 in 1940 and again at 17 in 1949. Freedom of speech in independent Latvia doesn't include waving a Soviet flag in front of her or her granddaughter. This is because it signifies mass deportations and nullification of Latvian sovereignty, just as a keffiyeh advocates the anti-semitic nullification of Jewish sovereignty and "yahud, go back to Poland." If you doubt this listen to Abbas and his imams on https://memritv.org and https://palwatch.org in Arabic when they think we're not listening.

And, just to be clear, employees' freedom of speech doesn't extend to advocating personal political preferences on employers' property under NY employment law. Call your lawyer as soon as he graduates from law school to verify this point.
