Don't have a lib in my family except my DIL. I just tell her she's full of shit and change the subject.
No offense DD, but..................
You ever whup a jackass like that when I'm around and yer gonna look awful funny walkin' around with that 2x4 hangin' out yer ass. Donkeys and mules get a bad rap. One of the most gentle and loyal domesticated animals around. Horses are way more temperamental. You'll never get saddle sores from a mule or donkey like you can from a horse. Total different gate.
I know, I've raised both. DUmmies on the other hand............ Baseball bat might hold up better to get yer message across. Prolly take a while.
One of my fellow co workers raises mules, and one of his customers is the Park Rangers for the Grand Canyon. His mules take tourists for rides to the canyon floor and back.
