Let me provide a counterpoint to Mats' post, which I genuinely appreciated reading.
The choice of conditions under which athletes compete fairly is entirely arbitrary. The point has been set, and is clear enough that, without too much diligence, it is easy to satisfy.
As in anything, a certain percentage of participants will follow the rules, and a certain percentage will break the rules. Any ordered system requires regularity and consistency to maintain itself, and needs the power to penalize and/or exclude those who break the rules, for a variety of good reasons that relate to the very maintenance of the endeavor itself.
There are those of us who have the maturity to recognize this, and apart from not wanting to suffer individual sanction, see the broader picture and want the endeavor to survive. Some idiot driving while high is, all other things being equal, a threat to society. The fact that he didn't run anybody over while dreaming up PCR is merely a result of luck. If he admitted wrongdoing, officials charged with the task of deciding whether or not to penalize his conduct have a job to do, regardless of whether or not he did concurrent good. Guilty verdict, with leniency in sentencing.
So, because we recognize that both our personal situation and the very endeavor are at stake, and have decided that the endeavor is worthwhile, we look upon the rule-breakers with disfavor. For obvious reasons--they are working at cross-purposes to our own.
The fact that you don't mind that you may have lost out to some doper points not to your resiliency, but to either your ignorance, your juvenile ambivalence, or to the fact that you don't see sufficient worth in the endeavor to make you feel otherwise. The first two of these are certainly nothing to which to aspire; if it is the third, you seem to have wasted a lot of your time involved in the system. In any case, the outcome is disappointing.
If you don't care, fine--but don't come in here and present yourself as someone who is an honorable part of the system. Competing clean yourself just is not enough to satisfy adult requirements--you must go farther in order to make a meaningful adult contribution to the dialogue.
If you are unwilling or unable to do so, that's fine. But don't waste our time in a failed attempt to appropriate the moral high ground.
