My sensor says that hurting kids is wrong, and anything that can help fewer kids get traumatized could be a good thing. My sensor would also be thinking "WTF?!" if I ever saw one of the products in question...
As you note, maybe some borderline types will be led down the bad path as well, but the mystery number that makes it possibly a "good" product is how many kids won't suffer because that latex product exists. Most likely we can never know that number, and so my point is entirely academic... but if it did... wouldn't that make it beneficial?
I think I gotta stick with my God-given Right-Wrong sensor. I gotta say no.
The brain might be convinced, but I’m gonna rely on my God-Gland instead.
