Lots of cheese is curdled using rennet, which can come from stomachs of killed calves.

If you check wikipedia, you will find that most is coming from GMO'd yeasts and moulds these days.

Okay?

Lots of European cheeses still use animal rennet, including several well known AOC (or PDO in English, I guess) ones with recognizable names.

I can check Wikipedia all I want but that doesn't make several of the cheeses I like to buy vegetarian.

Yup, exactly this. I’m European and prefer EU cheese, but many do use animal rennet.
