This is some fucked-up bollocks right here. People use swearwords for all kinds of reasons - for emphasis, to indicate anger or other emotions, to fit in with their peer group, etc. - but "avoiding reality" isn't one of those reasons. How would that even work? If I say "fuck" often enough, I don't have to worry about paying my bills or something? What a pile of shite.
Also, it's a bit rich for somebody who proclaims his belief in gods, angels, djinns and other such made-up shit to accuse others of avoiding reality. That's the world turned on its head, spun around until it's dizzy and left to fall flat on its arse. Avoiding reality - particularly the reality of death - is a huge part of believing the shit theists believe in, so to accuse people like me of avoiding reality just because of the occasional curse - well, you can fuck right off with that shit.
Finally, and I'm just throwing this in as an aside, did you know that swearing is an indicator of a larger-than-average vocabulary?

"A voluminous taboo lexicon may better be considered an indicator of healthy verbal abilities rather than a cover for their deficiencies," the researchers wrote. "Speakers who use taboo words understand their general expressive content as well as nuanced distinctions that must be drawn to use slurs appropriately. The ability to make nuanced distinctions indicates the presence of more rather than less linguistic knowledge, as implied by the POV [Poverty of Vocabulary] view."
So you can take your bullshit shot in the dark about (yet more) things you clearly don't understand, and shove it up your pox-ridden arse.
