I think the use of foul language and swearing is alright. Also, I think it might be sometimes necessary to cuss in order to get a message across with conviction because some people in this world are really "FUCKING" stupid. I can see were someone may think Phil from Pantera or Tom from Slayer may curse to much, but to me there just going with the flow and the emotion of the music in order to get the point or vibe across. I've heard Warrell cuss a few times live, but just because a person curses in his/her lyrics doesn't mean they're any less intelligent than those who don't cuss. Example: Mike Muir of Suicidal Tendencies/Infectious Grooves/ Cyco Miko. This man is very intelligent and writes poetry, but also curses quite often. My favorite lyrics from him are from the Suicidal Tendencies album LIGHTS, CAMERA, REVOLUTION and the song "You Can't Bring Me Down". I don't know the words exactly but he says something like, "sometimes maybe I feel like shit. I'm not happy about it, but I'd rather feel like shit than be full of shit." Another line he says, "Crazy, you call me Crazy? You wouldn't know what fucking crazy was if fucking Charles Manson was eating Fruit Loops on your front Porch." And last but not least, " Did I offend you? Well maybe you needed to be offended. Heres my apology and one more thing, FUCK YOU".
