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.
Trans women are women
One of the core dogmata of the transgender movement is the statement that trans women are women (and the less often repeated trans men are men). Under this view it's important to write trans woman as two words (adjective and noun) and not transwoman, to stress the fact that so-called trans women are literally a subtype of women, just like white women, black women, short women, tall women, and so on.
Since the statement contradicts the dictionary definition of the word "woman" (adult human female), it implies the desire for a different definition. When prompted, transgender activists rarely attempt to provide such an alternative definition. Most attempts tend to revolve around a circular definition, such as "anyone who identifies as a woman, is a woman." As such, the statement is most accurately described as a dogma.
The idea that transwomen are literally women is taken as the basis for many problematic conclusions, such as: transwomen deserve to partake in women's sports, transwomen should be seen as part of the natural dating pool of lesbians, transwomen deserve to use all female facilities, enter female-only spaces and events, speak on women's rights as women, and so on.
The idea that "trans women are women" is usually backed by a belief in an essential, inborn, and immutable "gender identity" that every person supposedly possesses. Transwomen are said to be real women on the grounds that they possess a "female gender identity" which they are said to share with women. Likewise for transmen and a "male gender identity" that is supposedly shared by all men.
Just like transgender activists refuse to provide an objective definition of womanhood, they tend to refuse defining gender identity on any objective terms. Usually, when explaining how a person has discovered their gender identity, one hears references to sexist stereotypes ascribed to womanhood and manhood. When confronted directly however, transgender activists refuse the notion that gender identity is based entirely on those stereotypes. Since no objective measure exists at all, they are effectively forced to accept the claims of anyone and everyone regarding what their gender identity is. Thus we see transwomen with full beards and intact male anatomy, who are said to be literally real women like any other.
Since gender identity is said to be inborn, it follows that some children are transgender, and only need to find this out. Once it's found out, the only way forward is to support the child in its transgender identification. This leads to the transgender activist "affirm-only" approach towards youth, where a boy who says "I wish I was a girl" or "I'm actually a girl" is from that point on treated as a girl (given a female name, referred to by female pronouns, asked by be considered a girl by others, and so on). Likewise for girls who express that they wish they were a boy, or claim that they are internally a boy.
Cisgender people oppress transgender people
Another core tenet of transgender ideology is the notion that cisgender people oppress transgender people, just like how men oppress women, white Americans oppress black Americans, or how straight people oppress gay men and lesbian women. As such, when a man identifies as a transwoman, his position relative to that of a woman turns from being her oppressor to someone who is oppressed by her. His male privilege is denied as he is now considered a woman, and the fact that he is a transgender woman means that he is oppressed by so-called cisgender women. Further, being both a woman and transgender means he is considered to suffer under two axes of oppression, akin to how black women suffer both from racism and sexism. This way, a white man suddenly becomes comparable to a black woman with regards to oppressive power dynamics in society.
