Please stop talking. You clearly have no idea what you're saying.
First you say only a retard would use an axe from horseback - People showed you examples of such uses.
Then you asked for more - People showed you more.
Then you said "well, I still think battleaxes are stupid because that's my opinion" - People tried to explain to you why battleaxes were chosen in certain circumstances.
Then you finally resort to calling other people daft, because yes.
Battleaxes were used quite extensively by cavalry all the way to 17th century England. You think you know better than the military experts of the time who were trusting their lives on those axes. Ok.
