As someone else said, it comes down to personal acceptance of risks, and being aware of what can happen. I'm very careful about checking for leaks and making sure there's an open exit and ventilation. Oh, and making sure I'm between the stove and the exit.
But of the thousands camping every weekend, mostly without incident, I'll take my chances cooking in or near my tent. There's always a fire extinguisher within a few feet in the car.
I hate gas full stop, have it in the house as its what was here when we moved in but still dont like it. Prefer to use electric induction hob when camping or eat out.

Fasten up 1 or 2 FIRE BLANKETS behind the cooker. I also stand the cooker stand on one. This prevents splashing bubbling stuff over the tent. I have them cliped with crocodile pegs so the blanket could quickly be pulled / detached and used in any emergency.
Having said that . Iv'e been camping for around 50 years and only know of one incident from when I was 10 yrs old where a small tent went up while someone on the site was using an old petrol stove.
As well as my normal 2 ring cooker inside the tent, I have 2 Campingaz screw on rings that fit direct to 904 or 907 cylinders and whenever I can I use these outside the tent.
As said above. It comes down to personal acceptance of risk. Every day we do things that could harm us.
Therefor , consider wearing goggles , asbestos gloves and a fireproof apron when cooking because you are more likely to be harmed by what you are cooking than actually cooking it.
Oh and don't forget the condom !
