I’ve heard spade used in a racist way in Texas, North Carolina (Fayetteville, Charlotte, Greensville) South Carolina (Myrtle Beach) Texas (Houston, Austin, Dallas,) Georgia (Atlanta), & Missouri (Branson, Forsythe, Sprinfield, Joplin, Kansas City, etc. etc.) so I figure that the commenters above professing to be from the South lead amazingly cloistered lives.
