Not liking meat sounds like a totally reasonable answer to me
For me, I eat it I guess for much the same reasons others have given.
* I grew up eating meat, so it's part of what I consider a 'normal' diet for me, it's in a lot of the things I know how to cook and it's probably partly habit to eat meat with 3-5 meals a week.
* I crave it sometimes. Sometimes for a piece of steak I'd cut the meat from my own leg to get it!!! (no... Not really...)
* and cos it TASTES GOOD!!! Mmmmm.
