Okay, ill bite. 
Your example is super polarizing but my point still stands. 
If you discovered that Albert Einstein or Stephen Hawking was a pedo, you’d be disgusted but it wouldn’t undermine their contributions to science.
One has nothing do with the other.
My only point. 
Normally I wouldn’t have bothered to reply at all but my hope here, is to enlighten a fellow bitcoiner.

 truth cannot be undone by the character of one who spoke it

but it can call into question how this speaker came by this knowledge... 

 For me, it actually would undermine and cast doubt upon their contributions. John Maynard Keynes being a pedo even further decreases his credibility for me. It demonstrates a corrupted mind that can corrupt all of their ideas.
