Lol.
Then it'd be the idiocy of the parents, if their kids grew up stigmatised with "WLs aren't good."

Babies didn't born complete with prejudices/Assumptions/Moral standards. You name it.
However you define it.

I'd say their kids grow up to find that the world is a better place without prejudices, without baseless moral standard about WLs.

So, as to not straying too far off the path of the thread..
Relationship with a WLs.

Of course you should have thought about this thing when you are going into a relationship.
How to deal with it. That's yours to decide.
Wehether you two decide to buy a dog. Or you two decide to have a baby.
