Earlier quoted context omitted.
I didn't say that you should support the idea of role models. I said that the argument provided in pjc50's post supported the idea that "role models are probably a bad idea". Your comment only included a sentiment, not a rational reason to support the idea you tried to express.
That's all that is needed when the burden of proof is not upon you. I don't need to argue why there is no teapot in space, anyone with such a claim themselves bear that burden. MY 'idea' is the rejection if an unsupported claim, requiring no more rationalisation than that.
In that case you didn't needed to write down your rejection of it either, and your post became redundant. No wonder that it got downmodded into oblivion.
