That goes both ways.
To be honest, you can bear the burden of proof yourself. If you want to show me I'm wrong, I'm more than willing to review the evidence. Unless of course you're just projecting the whole armchair thing onto others.
Lastly, if you think of it, asking others to prove the irrelevance of LDL with regards to CVD is straight non-sense. Do I also have to prove to you that wearing grey socks doesn't cause disease?
