If for no reason but authoritative education, I am posting information from Wikipedia. I've sectioned it up into more than 1 post so it will be easier to read.

P.S. I doubt it will change anyone's opinion, but interesting nonetheless.

History

The term "*****" comes from the 1150 word bicche, which was developed from the Old English word bicce. It also may have been derived from the Old Icelandic work bikkja for "female dog." The Oxford English Dictionary dates the term meaning "female dog" to around 1000 A.D.[1]
As a derogatory term for women, it has been in use since the fourteenth[2] or fifteenth century.[1] It's earliest slang meaning mainly referred to sexual behavior, according to the English language historian Geoffrey Hughes[3]:
The early applications were to a promiscuous or sensual woman, a metaphorical extension of the behavior of a ***** in heat. Herein lies the original point of the powerful insult son of a *****, found as biche sone ca. 1330 in Arthur and Merlin ... while in a spirited exchange in the Chester Play (ca. 1400) a character demands: “Whom callest thou queine, skabde *****?” (“Who are you calling a *****, you miserable *****?”).
"*****" remained a strong insult through the nineteenth century. The entry in Francis Grose's Dictionary of the Vulgar Tongue (1785) reads :
A she dog, or doggess; the most offensive appellation that can be given to an English woman, even more provoking than that of *****, as may he gathered from the regular Billinsgate or St. Giles's answer--"I may be a *****, but can't be a *****."[4]
