Rick Allen is a great person for continuing with his drumming career with one (1) arm. Nobody's claiming he's a "great drummer" and your insensitivity doesn't contribute much here. The comment section is not a record store.
Many people have stronger voices than Page, but the point still stands that it's how you approach your adversity that counts.
In all fairness to Mel Gibson above "Several of the beats on that album became legendary" would seem to imply he was a great drummer. I agree it's rather odd to take issue with what was an unusual analogy to begin with but it was hardly an outlandish response/comment.
Mel Gibson? I don't get that but his response was fair and considered and correct. The OP trolled a highly subjective argument about who's the best drummer which completely missed the point of the original comment and the entire story.
