What about the " S " Word ?

Everyone knows you can't use the " N " word with out risking riots in response or at the very least, a bad outcome. And of course the use of coarse language in a hurtful manor is always uncivilized.Personally since becoming an adult , I try to avoid crude language as a matter of self respect.
I am fond of language, especially the semantics of the English Language, as spoken in America. Portuguese Navigators of The Fifteenth Century purchased slaves from Islamic dealers in Nigeria. The people so sold were Niger's from inland Nigeria. So it would seem that that's where The " N " Word stems from.
The latest hullabaloo,that has come to my attention is all about The " B " Word ! Some women are more sensitive to it than others. And their ire, or lack there of seems to be predicated on two indicators. They are which gender is doing the talking , and is the race and speaker the same , or different?
Now we all know it's perfectly fine to use the " B " word, as long as your talking about the better half of the Canine World. But even then, one usually is very careful in polite company.....
Then there's the " F " Word. No! Not that one!! No, I'm talking about the one I cautiously looked up in my older brother's dictionary,when I was around twelve years old. Low and behold, there it was! The Dictionary's given meaning mystified me... I couldn't figure out why the guys at my newly attended public middle school, would throw the word out with such knowing bravado? The Dictionary said it meant" A bundle of dried sticks prepared for burning. " What?!!
Now days I am mystified by a new derogatory word . Apparently it can be used to malign any person, place,thing or situation...The "S"Word is " S U C K S " . As in " Well that sucks . " I know I started hearing it used in common language a few years ago. I think? But now I hear it used on sit-comms on TV prime time. As an amateur semanticist it unnerves me mightily, to not have a complete understanding of the word as used in the English Language.
As one that shays away from crude language, except in very unusual circumstances, I don't know if I want to use this derogatory word ; or is it a euphemism ? After all, Sucks What ?!! Is it now bad, for instance to suck on a soda straw?If the vacuum cleaner sucks up the dirt, is that not good? I guess if a white tornado came into my laundry and sucked the dirt out of my clothes...Or was that Mr. Clean ? Well anyway you must catch my drift.....

Say next time let's talk about The " G " Word ! You know the one. It used to have a very pleasant connotation...I can think of at least one very popular Christmas song that it was contained in, and it's a synonym for happiness, right? I really strongly resent it being co opted in modern times.....
