@Deja_vu, that is a pretty belief, but in my experience it’s not borne out. Rather, the lies are likely to be believed by some, and the people who see the disconnect between your behavior and the false accusations will just think you are a damned phony and accuse you of trying to dupe them by playing the injured innocent.
People who choose the route of lies and slander and false accusation as a way of getting something they want do it for one of two reasons, or so I believe: either (a) because they don’t have what it takes to get something fairly and on their own merits or (b) because they simply enjoy the duplicity and manipulation in the same way that some people enjoy trolling online. Either way, a sincere, honorable person is never even going to imagine what someone might be thinking of or doing or saying against them and might even play into it completely naively by “being true to himself or herself” in a way that others can misinterpret.
As soon as such a person catches on and tries to defend himself (let’s just say “himself” for simplicity), he is apt to run into wily counterattacks that he is completely unprepared for and may also set others to wondering whether he is just a whiner trying to blame others for his own problems. Where there’s smoke, there’s fire, they will say.
Someone who’s willing to play this dirty game in the first place will have no compunction about twisting the victim’s attempts at self-exoneration. The innocent is no match for an unscrupulous person, no matter how many movie scripts, sitcoms, superhero comics, and moralistic children’s books turn out the other way.
And it does matter, because people’s reputations are easily destroyed and difficult to regain, maybe impossible; the whispers will always remain; and because in the workplace in particular, it is not just a matter of comfort but of perceived performance, eligibility for recognition and raises and promotions, loss of safety margin against layoffs, etc. Even if they know you’re innocent, they can want to get rid of you just to make the tiresome controversy go away. False accusations can literally cost you your livelihood.
I don’t see that there’s much that can be done about it. One’s true friends won’t believe it. But one can suffer much harm from such malicious backstabbing, and it may never be possible to put it right. I think we are foolish if we believe that by ignoring it we can become immune to the effects.
Liars tend to think others are liars. Honest people seldom expect others to be liars, and their honesty leaves them defenseless.
