To those who deem this sick:
Who are you to determine what is sick and what is not sick. Society
does not vote for you to determine what is sick and what is not. It
is funny how people would have a more subdued reaction with regards
to inserting silicon into mammary glands, beastiality, incest or
murder. In any case, I think murder is worse than what those guys
are doing to their bodies. But would "sick" be the first word that
appears in your mind when you heard about murder? Most likely not.
The reason is because we grow to accept it due the frequency of the
matter.
These people are in no way sick. What is demented is how society
has structured your mentality.
