I'm out of variations but if you make a claim post a source. The previous commenter has been downvoted for (rightfully) asking for evidence to accompany its claims, you double down on providing no evidence and making even larger claims.
I'm not saying you're right or wrong, but if you make a claim and don't provide evidence you have presented a non-argument.
I think its self evident why that is a poor approach to understanding anything other than your own opinion so I wont bother explaining why to you, I don't think you'd care.
