It doesn't. Actually using that argument means you agree with the concept that it is a playstyle difference.

Eating meat is bad. No it's lifestyle choice, it's just that YOU don't find it appealing.
Not eating meat is bad. It's just that YOU don't find it appealing because it doesn't fit your lifestyle.
Both statements agree that it's a lifestyle choice. Which in turn invalidate the good/bad argument.

It's a play style choice. Not liking it just means it wasn't designed for you.
