Heightism denial

I left r/short because of the blatan denial that heightism is a reality. The people on r/short refuse to acknowledge that heightism is a problem. They live in this fantasy bubble and keep on saying to themselves how great being short is. And always talk about its about confidence. No its not about confidence. Short people are being marginalized. I really don't understand their mentality. I don't understand why they have chosen to deny heightism and pretend it doesn't exist. I am starting to think they believe in a hierarchy that short people should be at the bottom of life. I don't know but I hate r/short.
