I'm not American, I'm from the British Isles, and, from my perspective, very few environments or social or work settings, or contexts justify the use of crude language. Understanding context, and that different forms of language are used in different settings and contexts is just basic manners or an awareness of social calibration and one's environment. Again, employing a "sophisticated use of language" does not equate with being uptight socially, and it is something of a fallacy (or perhaps a prejudice) to assume a link where none exists. Absolutely; I couldn't agree more. The use of crude language may reduce the level of stress of those who use it; I doubt it does anything to relieve the stress of those against whom it is used, or to whom it may be addressed. Again, well said and I am in complete agreement with you.
