As always, comments/feedback/criticism welcome.Transgender ideology is a loose catch-all term referring to philosophies, world views, and dogmatic statements adhered to by political activists who see themselves as trying to uphold the human rights of transgender people. The political movement of furthering these ideologies is called the transgender movement. Feminists tend to use these terms critically when pointing out sexist, homophobic, or otherwise problematic aspects of the movement. Those who support the transgender movement tend to oppose the term transgender ideology, likening it to phrases such as homosexual agenda which is used to ascribe a sinister intent to gay/lesbian/bisexual rights activists.
The practice of supporting transgender ideology is called transgender activism (often shortened trans activism) and a person who follows this practice is called a transgender activist (often shortened trans activist). The word "transgender" in the phrase "transgender activist" is not to be understood as an adjective for the person in question (i.e. "an activist who happens to be transgender") but as a reference to the activism they practice (i.e. "an activist supporting transgender ideology"). Many trans activists are not transgender themselves.
The term trans rights activist (shortened TRA) is sometimes used for its similarity to men's rights activist (shortened MRA). Just like so-called MRAs claim to support men's human rights but end up blaming everything on women and opposing feminism, TRAs claim to support transgender human rights but end up blaming everything on women and opposing feminism.
