Most people use these words (and they are just words) out of habit and don't even realize the full meaning of the words. We make a big deal out of nothing.
Swear language was never the purpose of God creating man. Mankind was made in God's image, to reflect Him, for His pleasure. His language is clean and pure holy. Anything else than that is offensive is categorised as not good not good enough. Peace.
To me a person that swears has a very limited vocabulary and could correct this by studying more english and frequent the dictionary.
Swearing depends on the people or person your talking to calling someone a idiot/moron/fool/might be more offensive than if you called them an asshole there really isnt any reason for swearing but in today's society it seams like you just cant get your point across to certain people unless you swear at them i try to avoid those type of people but i have been known to blurt out a few choice words myself never use the lords name in vain it is one of the easiest commandments to follow .
