Let's sawp it all out for 'vegetarian'.
I'm vegetarian I identity as vegetarian. Simples, no?
Really, unless you're in some way intimately involved in my life, it doesnt matter.
Oh? Dio's vegetarian. K, neat. So, how was your slots day?
To my immediate friends and family it might all become rather complicated, especially if you're making me food..am I vegan? Pescatarian? How PRECISELY do you identity. Do you have food allergies? Medical concerns? Is it preference? Personal?
Otherwise, who gives a fuck, right? It in no way impacts your life. Doesnt matter if youre vegetarian, or your neighbour, or brother or sister or your kid.
Now you can put the other words back in.
