What a surprise, a girl has to fight more and deal with more crap than her male counterpart to be herself in a shifting patriarchial society. I never would've expected that.
Frankly it's true; generally speaking life is harder for INTP girls because girls, for the most part, are expected to be, well, maternal. Being maternal means loving and caring and supportive, and even so these maternal types are supposed to be sociable and sweet. And for the average INTP woman, it can be difficult to express such feelings, but frankly it's not just INTP girls that face such a problem. It's just about any woman over the age of 30 who is unmarried or has no kids, or any woman who is single and expresses no desire to have women. It's not just INTP women being affected here, but that's a whole other story.
Although, to prove the validity of that statement, I will share an anecdote. My 40 year old cousin, who was 38 at the time, was having a lunch with her brother and sister-in-law. This woman has no job and her only aspirations in life were to become a mother. At the time she had three kids, fourth on the way. She told from my cousin, her in-law, that it wasn't right her kids weren't going to have cousins (a year or two later they did get one, but it was a girl and not a boy so it basically didn't count... my family's a little messed up on this section of my mom's side), and how as a woman she was bound to bear children. My cousin, being who she is, just stared at her all deadpan and said that she is happy with where she is in life now and that's the way it's going to be. This in-law then went on to say that if my cousin wasn't married or had NO interest in children, then that MUST mean she's a lesbian. My cousin is a great person; she is a middle-school teacher who is an avid outdoors person and traveller, she has many friends, of which some have kids she enjoys talking with and taking out on adventures, and she's happy with her single life and very much appreciated by her colleagues. She's tried dating, mostly online, but it has done nothing for her. Yet as soon as she shows no interest in having children of her own or a husband, let alone a long-term boyfriend, she's a failure as a woman.
[[needless to say, she has NOT gone to visit - or gone out of her way to keep in contact with - this brother and in-law since, but rather enjoys telling this story at gatherings]]
Honestly, in high school, I was HAPPY to be INTP. I wasn't so socially awkward that I was a prime target for bullying, and I wasn't so sociable and otherwise extroverted that I drew attention to myself enough that rumours would spread about me. I could talk with the more popular crowd if I needed to, and I could even inject into their conversations without being put down; sometimes they even appreciated it, occasionally to the point of being welcoming. But oftentimes I was just left alone, and with me I would have a friend or two, or be all by myself. I was never bothered. My bestie calls this "the void", a place where one is not popular enough to befriend the "cool kids", but not enough of a loser to be made fun of. It was perfect! Lonely at times, and occasionally frustrating mostly due to the fact I felt I couldn't correct said populars when they were trying to have an intellectual conversation but were saying the stupidest things, but otherwise it was great.
While it can be a pain to be an INTP girl in terms of the expectation of females in society, sometimes you'll find the right person who understands you enough to accept who you are and still want to be with you. It can be harder for us than others, but more often than not we're willing to wait, or in the least not be so bothered by it that it's crippling.
It all depends on what you let bother you, ultimately. If you're an INTP woman and having strong feministic values, life will be rather harsh through your lens. But if you just accept that you're different, it usually won't seem quite so bad.
