I am not claiming that reality is subjective. I am claiming that the fact that there is not a consensus as to what behaviour is considered acceptable is evidence that no one person can believably claim to have a privileged view as to what *is* correct. Reality is clearly not subjective, but ones interpretation of reality is, by definition. So, while you claim that certain behaviours are not healthy or acceptable, it ultimately comes down to being able to prove that the actions you are condoning (namely, prohibition of certain online content such as bestiality and violent pornography, as well as social stigmatization of obesity) will have a positive effect on society. And it is at this point that it comes down to what one values more, the sanctity of freedom of expression, or the need to preserve your personal sense of "morality" or "wholesomeness". Ultimately, YOU are the one who is pushing your personal and arbitrary standards on others by encouraging legislation that outlaws certain types of information.
With regards to obesity, you point out that it is a scientific fact that obesity leads to health problems. That is all well and good, but my point was that who are *you* to *judge* others for their life choices? Smoking is also extremely unhealthy, but I don't go around pointing fingers at and chastising people for choosing to smoke. It is not your place to tell people what they should and should not do with their own body. Yes, people should be made aware of the consequences of their choices, but discriminating against them for making life choices that you find unsavoury is not acceptable.
