I had to look it up too... I remembered the word existed and that "sinister" was in it but I couldn't put the whole thing together.
Which by the way gave me renewed hope about the neutrality thing. (Looking up that word.) It really did used to be a big deal for people to be left-handed. And now we have a president who is no stranger to gratuitous slurs and insinuations yet I don't remember seeing a thing about "gasp, he's left-handed! that proves he's evil!"
People are born with a predisposition to being left-handed or right-handed. Sure, you can force a left-handed person to write with their right hand, but, WHY?
We're probably at least 25 years out (50? 500?) but hopefully that's how things will pan out with the whole homosexuality thing too.
