I'm not discounting sexism, either, but I think that it has less to do with bias toward T in this sake as much as it is just bias towards men in general. Likewise, I don't discount that Fi-users often get the short end in general. Dom/aux male Fe-users are very commonly respected for the grace and aplomb they use in their interactions, their trustworthiness and reliability, and quiet gravitas, depending on the other functions. At worst, these types are "overbearing", "manipulative", "shallow", and "predictable". Unfortunately, their Fi-dominant/auxiliary counterparts rarely get the same level of respect.
At the same time, though, you're kind of making my point for me as well - men with highly-developed T functions are often respected for their analytical and organizational skills, but at the same time decried as "cold", "heartless", "thoughtless", "assholes", "arrogant", "uptight", "rigid", "smart, but just doesn't get it", "dictator", "fascist" and so on, and so forth. Women with highly-developed T functions are described as "ice queens", "cold", "tomboys", "dykes" (much like men with dom/aux Fi are commonly thought to be gay), "dragon ladies", "sluts", "bossy", "flighty", "random", "not maternal", so on and so forth.
So yes, when it comes to disparagement, I think when it comes to the entirety of the T function, we get much more criticism than F-users in general, however, I'm not unwilling to discount that the world of shit Fi-users have to deal with may equal or overwhelm these criticisms. Yes, the Fe-dom/aux get off way too damn easily in this department.
