Well, the first one straightforwardly says that they have nothing against LGBTQIA+, and KidRex may not know what you're trying to search for when you search that.
I also think that on KidRex, by the way they drew that on there, that it's meant for really, REALLY little children, and they probably don't want to tell them about it JUST yet, because they are still learning the basics of life x3
I dunno, that's just what I infer. I don't think that any of these sites would just flat out say that they don't like LGBTQIA+.
