Ooh, nice attempt at handwaving there. Good try though.
My sources are internationally renowned as authorities in the fields of medicine and psychology. Your "sources" are bunk:
Psychology Today is not a scientific journal. Their standards are notoriously poor in the field and have been frequently known to publish questionable material, so referencing them is meaningless. They are a pop science magazine and their material is often inaccurate or out of date.
That particular head shrink of John Hopkins is named Paul McHugh, whose research has repeatedly been labelled problematic and his conclusions deemed highly questionable by his peers. He has been pretty extensively discredited in many areas including post-traumatic stress disorder, sexual abuse, transvestism, homosexuality and dissociative identity disorder. He also happens to be a member of several right-wing conservative think tanks, and has known and acknowledged biases in that direction.
The American Psychiatric Association's latest document is the DSM-5, which is already almost three years out of date, having been approved in December 2012. It has also been highly controversial in recent years, which has led to it becoming the subject of at least two congressional investigations regarding a number of conflicts of interest detected, especially in the fields of gender and autism related syndromes. It has also faced repeated criticism on an international level for ignoring major studies done in countries outside North America.
That being said, even the APA does not agree with your belief that the best treatment for sufferers of Gender Dysphoria is behaviour modification, and no accredited source exists that supports your assertions that it is healthier to refuse to "pander to their delusions" than to engage and accept them. Not a single one. In fact the APA itself supports the opposite - engagement and acceptance, specifically determining that using the gender pronouns that the patient prefers is the healthy option and aids recovery and treatment.
So, then - your beliefs are based on discredited bunk and obsolete science and nobody agrees with your assertions regarding treatment. Your implication that ridicule, belittlement and deliberately using incorrect gender pronouns is somehow in the sufferer's best interests is quite literally nonsense. It is nothing more than an attempt to (rather badly) disguise your prejudice and bullying as kindness, to make you feel better about the way you treat others.
