Why? Because they’re “racist” of course.

From the Mirror:

Free sombreros handed out at restaurant BANNED by university chiefs – because they’re ‘racist’

Killjoy university chiefs have banned students from getting free sombreros – claiming they’re ‘racist’.

Students were being given free sombreros by a local Tex-Mex restaurant in a bid to drum up business , before uni chiefs ordered them to stop – because it violates strict cultural appropriation rules.

The University of East Anglia student union officials even took the big floppy hats from students at the Freshers’ Fair, because non-Mexicans wearing the traditional item of headwear could be seen as offensive, according to a new initiative.

The Union has stated that the handing out of sombreros breached a key advertising policy which was sent to all stall holders before the event, prohibiting any use of stereotypical imagery in advertising.

It read: “Discriminatory or stereotypical language or imagery aimed towards to any group or individual based on characteristics will not be permitted as part of our advertising.”
