The appropriation of the keffiyeh as a fashion statement by non-Arab wearers separate from its political and historical meaning has been the subject of controversy in recent years.[26] While it is often worn as a symbol of solidarity with the Palestinian struggle, the fashion industry has disregarded its significance by using its pattern and style in day-to-day clothing design. For example, in 2016, Topshop released a romper suit with the Keffiyeh print, calling it a "scarf playsuit". This led to accusations of cultural appropriation and Topshop eventually pulled the item from their website.[27]

Definitely not the same thing as a swastika or Klan hood, but there's a good argument against Western appropriation, especially by right-wing military types.

Basically, they're saying Palestinians hate Jews. Which statistically speaking, more than half of Gaza hates Jews. Not just Israel, they hate Jews in general.
