theres a few things involved with this...here in the USA when a treatment provider calls someone a fag or induces their clients to do so its called discrimination and grounds for losing their credentials.

theres also the situation that if your sons father is gay its illegal for treatment providers to act on this now. (its a hate crime)

theres also the fact that you have schizophrenia (in the past you have posted many times that treatment providers were telling you to do bad things, while at the same time posting about not taking medications) just on the odd chance taking this into consideration it could be a delusion/hallucination that we were telling you could happen in the what would happen if a schizophrenic didnt take their meds thread)

all these factors together tell me to suggest first contacting someone in the mental health agency that you trust and tell them what happened. they will be able to work out this situation with you, they can also officially report this person to the right places that can arrest this treatment provider who is telling you to commit hate crimes,discrimination against your sons father.
