Experiences of a Master’s student

I’m a Master’s student currently finishing a degree that contains specific philosophical subdisciplines. My experience so far is that:

a) an external speaker, when speaking about a general concept of a philosopher, used the “he” pronoun (he was speaking English, so he could’ve used the “they” pronoun instead to be inclusive);
b) a fellow sudent was asked to provide an example of empty intersection of two sets and he replied with “a clever blonde woman” (there is a single word for “blonde woman” in the language of instruction);
c) our lecturer of Philosophy of Science laughed at the idea that a man or a white person cannot fully comprehend the women’s experience or a PoC experience, without going into detail about this philosophy even though it was part of his lecture;
d) a PhD student from the department was explaining to us something about scientific conferences during a lecture and he said, “When they want to present such idea at a conference, they say, ‘Gentlemen, I have found /…/'”;
e) white men are everywhere in the curricula even though they didn’t publish a single thing during their lives, but I, as an ethnic woman, cannot expect a worldwide recognition unless I have zillions of articles in top notch journals.
