re: that "lesbian" in contra's replies...
i wrote a fucking essay, forgive me.
it's maddeningly easy to tell the difference between a trans lesbian and a real one even with no pfp or images if you are a woman, are a lesbian, or have grew up around and befriended women and lesbians on a deeper than surface level.
on the whole, lesbians hardly think about or talk about their lesbian identity unless they are at an actual lgbt event or with other gay women, basically any time it is relevant, sometimes out of shame or a long process of acceptance, sometimes because they have hundreds of better things to do. unlike male nerds, most lesbians are not online 8 hours a day, unless they are sixteen or maladjusted (and that's the age where you will likely see the most real ones). it's not a lie that they do art and sports and hiking and gardening and a number of other things, and typically have a job and a girlfriend depending on age. they have many hobbies outside of their lesbianism. very few are into anime, programming, or porn.
which brings me to my next point. usually, all males pretending to be lesbians know, and typically who they end up dating, is other males pretending to be lesbians. the reason for this is that they are typically incredibly socially awkward, don't pass, are selfish, and don't even like women as people. but to further explain it, and this is something most people don't get... lesbian doesn't mean you are a girly girl and you talk about how much you love girls. lesbian isn't solely about being a homosexual woman. it's typically about being socially conscious, mature, and no nonsense, protecting and providing for other women first and foremost. it's about rebuking femininity to please the male gaze and reclaiming it at various degrees of intensity to please other women. so that typically means not watching porn, because most lesbians see it as centering male violence and fantasies. that's kind of their thing, not doing things men can sexualize.
lesbianism isn't about sleepovers and pink and almost all lesbians are gender non conforming in some way. males pretending to be lesbians literally are only focused on appearance, stereotypes of women that are offensive to lesbians and that they want to more or less get away from, and talk about nothing but being a "cute girl", a lesbian, infantile bullshit, things they've seen in porn, how much they like feminine women presented through the male gaze, celebrating models and celebrities and women who have had work done instead of the reality of women...
so tl;dr here are the warning signs of a "stealth" transbian or one with no pictures.
1. obsessed with themselves, their appearance, and sex / fetishes. (the flip side of this: they fucking hate ugly or butch women and prudes/vanillas)
2. no hobbies outside of anime and other tv, video games, and computer touching.
3. zero interest in any women's rights issues beyond corporate feminism / corporate lgbt rights (you will NEVER hear these fuckers talk about how women are treated in other countries or how they are oppressed based on their biological reality, just microaggressions.)
4. other transbians circlejerking in their replies.
5. into surface level popular memes they think make them girly like cottagecore, goth gf, useless lesbian, pfp is nothing but the lesbian flag, etc.
6. last but not least they are always jealous of and resentful of real women and real lesbians.
7. infantilism and desperately trying to please. the hallmark of a lesbian is typically maturity and independence.
sorry for the book, i hope it can be mildly useful.
