Jesus dude no need to write a wall of text over a different opinion about TF2 weapons on the internet.
I say that you're the ignorant one, because you obviously can't adapt to different playstyles, or respect other people's opinions. Homewrecker is useful, and that is fact. I've seen my post, 15 people agree with me, and the 4 people that disagree with me are the people who compare it to the Axetingisher, not the default Axe. Coincidentally, all those people are rude and can't respect opinions.
Oh hell, this Spy just stabbed this Engineer, and left all of his buildings sapped, now we are defenseless. Oh wait! I have the Homewrecker! *Unsap*. Oh boy, the Engineer's buildings will now be available to provide us with defense while the Engineer respawns, and he won't have to go through the trouble and vulnerability of building them again!
How is that useless. It isn't all about getting kills. It is more about being a team player, and helping your team win.
