O.K.
However, and slightly aside from the topic....or person....under discussion, methinks the term, “calling a spade a spade” actually originated in reference to gambling with playing cards.
From wikipedia:
The phrase previously appeared in chapter 1 of Joseph Devlin’s book “How to Speak and Write Correctly” (1910)[2] where he satirized speakers who chose their words to show superiority:
For instance, you may not want to call a spade a spade. You may prefer to call it a spatulous device for abrading the surface of the soil. Better, however, to stick to the old familiar, simple name that your grandfather called it.
