It might be. Why compare stuff? It's not a fucking contest and I'm sick and tired of invalidation by comparison - cf. You're hungry? What about the starving children in Africa? You're in pain? What about people dying of cancer?
But is anyone saying it's just wonderful to have children's parents die or surrender them? Is anyone advocating doing this to children on purpose and intentionally? I doubt it. Because everyone realizes that not being raised by your biological family is not the ideal situation. And thus not something to be encouraged and advocated for.
So, by acknowledging that our situation falls under the same category as that of children who by unfortunate circumstances find themselves without their biological parents, shouldn't they also acknowledge that this is something you don't do to children on purpose?
