You can vent all you want, but it will not change the fact that the term, “calling a spade a spade” originated with poker players. The word “spade” also has been known to have racial connotations in some regions of the Country in times past.
Good evening.
Venting? Quoting someone that says different from your OPINION (you have shown nothing that proves your assertion) is hardly “venting”. Go away and come back when you have something that resembles reasonable intelligence.
And, yes, I am aware that blacks have been called “spades” as in “black as the ace of spades”.
