It's simply not readily available
It's easy to eat halaal when every corner has a halaal restuarant or butcher.
You're telling me if you lived in this country you would simply give up meat just because halaal was not easy to come by
You're telling me if you went to your Christian friend's house and their mom went out of her way and made chicken because "I know Muslims don't eat pork so I made you chicken" you'd be like nah fam it aint halaal init
This is extremism if I've ever seen it. Nowhere hadith or anything does it say become vegetarian if you can't eat halaal
