Don't they? My housecat has been known to curl his insanely large paws up into fists when he hits people. I've tried to teach him the ways of peace, but he is a cat, and also it is sort of funny when someone comes to me and says "um, so your cat just punched me"
I think the reason is that very few people have ever run into a lion in the wild. I think one encounter would probably change the a lot of people's mind in that regard.
Considering what a pitbull can do to a human being, imagine what 750 lbs of pure muscle and teeth will do?
Mom had mountain lions rescued as cubs. When I was 20-something, and much more badass than now 😅, I decided to fight Tasha on the living room floor.
That 90lb., declawed girl opened a 55-gallon drum of whoop ass on me. I'd tell you about, but I didn't see it. All I got was a tawny blur and I was on my back getting my hat forcibly removed, along with a healthy hank of long hair. (She hated men's hats, no one ever found out why. Not men. Just men's hats on a man's head.)
I no longer have any illusions about fighting a rabid 'possum.
If an animal was trying to kill me, I wouldn't mess with anything larger than a chicken. Even then their feet knives have a good chance of sending me to the emergency room.
I saw a lion at the local zoo a few years ago. I made the mistake of looking at his eyes. He got mad and slammed against the glass. I'm confident I could not win in a fight against a lion.
About 6 years ago I took one of my kids to the zoo and we were at the lion enclosure, all the lions just chilling and right as we started walking away one of them stood up and roared. Holy fuck are they loud, like a concert speaker just as loud and could feel it on my insides. My son absolutely shit himself and just laid down on the ground crying.
