As the sibling poster said, this isn't insulting another ethnicity's cuisine, it's insulting the quality of the product on offer in much of the UK.

I'd invite you to do a comparison. Here is a picture of a 'real' doner kebab or shwarma style kebab, raw - https://www.jidlonacestach.cz/data/obrazky/2026/01/pripraven...

Notice the recognisable layers of meat and fat, the cap of fat to melt in and keep it all moist.

Now here is what you're more likely to get in most generic UK high-street kebab shops - https://www.kirkskebabs.co.uk/raw-kebab-meat/

Notice the homogenous, pink-slime sorta texture going on? And take a look at those ingredients...

Now, if you're going to places serving the former, cool! That's probably some tasty eating. But the latter is why kebab shops in the UK are held in such low regard.
