In the Gerardo Furtado answer to Why does it hurt the next day after doing significant exercise?, I had a comment asking about whether the mechanism described had sound scientific basis. This comment was deleted, but the issue is the answer contains information addressing my comment. Moreover, the comment had several upvotes yesterday and is actually referred to in the answer with a broken link. Now the answer reads reads '... [comment] now deleted, next to that broken link.
Why was this comment deleted? Is there something wrong with asking questions like this? The author felt it compelled to address it in the answer. I'm confused. Is it against the rules here to ask questions about unproven hypotheses?
