Sadly, I am not so young, nor am I trying to hurl insults, I just have a difficult time understanding how people can be so opinionated about what others are doing when said actions have zero effect on them personally.
A robbery on the other side of town wherein someones life is taken has no effect upon anyone other than the victim. It is still a crime and you are selected for the jury but as the crime in question has had zero effect on you personally you must recuse yourself because your opinion is invalid. This in spite of it being a felony.
Someone runs a red light and they just miss hitting your car, but since it has no lasting affect on you no one should care. It was still breaking the law and a LEO was present but decides against writing a ticket because you were not personally affected in an manner that will last more than a few minutes at best. No harm, no problem. Again, in spite of it being a genuine offense you were not personally affected (i.e., harmed in any real way).
You are mugged but they drop the money as they run away. They are caught within minutes but the police decided to let them go because after all, you still have your money and they didn't actually harm you. Yup, you guessed it. You were not personally affected. No harm and you still have your money.
We cannot pick and choose the laws you obey. You can state that steroid use is nothing compared to my analogies, but it is against the law to use them without a prescription and they are banned from many sporting activities/competitions. We can rail against laws and quite possibly break them either in protest or as a matter of personal habit or disregard (and many people do) or we can work to have them changed or removed but that is up to we the people and our system of government.
A friend of mine once told me that different people have different levels of disgust. By that he meant that we all tolerate that which is immoral or illegal according to our personal level(s) of disgust. It has nothing to do with being "better" than anyone else, instead it is based upon what we will or will not accept as good and evil or right and wrong. I think PEDs are cheating no matter if one or everyone engages in them. I think murder is murder and robbery is robbery. Morality is not really all that relative with the caveat of again, what a person is personally willing to overlook. Or not. It really is that simple.
