What is being attempted here is to confuse the distinction between actions and attractions. It is attempt to bring sympathy to innocent people. Once this is done then the next stage is to legitimize the acts.
Yes. I think deviants of all stripes are watching and noting “what works.” For example, a web page for sociopaths is agitating for sociopath’s rights, posting their denizens and innocent victims, whimpering that they shouldn’t be discriminated against, sneering that “empaths” (that’s normal people with empathy) are the “real” monsters to be feared for their bigotry, etc. Really, is there nothing living under rocks and at the bottom of cesspools that won’t rise up and demand its rights?
