I mean if this isn't equating trans with sex offences then I don't know what is:
"Transgender fetish is the largest sexual disorder reported in convicted sex offenders.(4) Almost 100% of convicted sex offenders have a documented history of transvestism, crossdressing, free-dressing, Autogynephilia, transsexualism – in other words: TRANSGENDER."
That link has really dodgy stats and is implying extremely strongly that all MTF trans people are deviant sex offenders.
Even using that authors extremely wide definition of transgender, I flat out do not believe that nearly 100% of all sex offenders are transgender. That is just hatemongering bollocks, quite frankly.
Having said that I don't know what "free dressing" is - if it means "wearing clothing" then maybe the author has a point. I somehow doubt it though.
