[cybernautique]

I quibble with your notion that this argument needs be logically sound in the first place. Logic is about consequence; this is a question of values.

It is my value judgment that Facebook is disgusting, and my arbitrary desideratum for this judgment is that Facebook (allegedly) spun a narrative to cover their suicide machine.

You'd be right in saying that this line of thought is decidedly not sound; nor could it ever have been sound in the first place, because it's irrational and arbitrary. Does its irrationality and arbitrariness make it less valuable than logically sound arguments? If so, why?
