Early methods of starting a fire included rapidly「twisting for emissions」a stick with firm pressure against another piece of wood until the end began to smoke and sported an ember due to the heat of friction…this woody stick with hot tip was known as a FAGOT (FAGGOT). When the fagot (faggot) tip started smoking, it was time to「stop the twisting and screwing of wood by the sitting person」performing the fire-starting function, begin blowing to fan the flame, and set alight the tinder and kindling prepared and piled nearby, then continue hard blowing until flames consumed the whole cluster of woody material. DebunKanji does not state a moral opinion regarding the use of these terms to describe homosexuality of either sex, but is simply explaining how and why the use of the terms originated, and the glyphs behind that usage.
　「This here wood」as FIREWOOD, wood that will later become flaming, burning, on fire.
　「Cease, stop」with「sitting person, no-longer-integrated feet person as service provider」with「screwing emissions, woody」and in their stead select「here, I'll take this one with the woody」that smacks of a lord or clients having a preference for male service providers…in the case of dynastic China, it becomes clear how homosexual males came to be called by the epithet FAGOT (FAGGOT). If no one comes and then pays for sexual services with the females and their no-longer-integrated feet, those service providers would not be fed well, would not become piggish lardasses, and would remain LEAN, likely starving eventually since no other work was possible for them. Not equipped with deliberately no-longer-integrated feet, male homosexuals may have been able to exercise somewhat normally, remaining LEAN, THIN, NOT FAT and not becoming obese as did many of their counterpart female concubines and service providers:「cease with the sitting people for woody screwing emissions」suggests using someone else for that matter.
