When I was a religious zealot I used to cringe when someone used the F word. I was so holy (translation:judgemental), and self-righteous.
It is humans that give meanings to words. Words are neutral, until they are given meaning. What if the ‘bad word’ was Fish. And I would say with emphasis to you FISH YOU! Do you now see how ridiculous that freaking out over the F word is.
I have used the F word mostly when dealing with BRAINWASHED Christians. It express exasperation and frustration at utter stupidity!
