class is 70% women

Because the post was written by someone who clearly feels that these women owe him their attention.

I assumed it's a women's studies class because the kind of male who feels entitled to attention like this would typically think something along the lines of "women's studies would have the highest ratio of women to men of any other class" and so join said class assuming it would be a good place to get a date.

The tone of the post implies that he is upset after realizing the course would not double as his own personal harem of desperate women fighting each other for his affection.

The reactions of the women he mentioned is why I assumed he probably doesn't bathe. I'm guessing he showed up in stained sweatpants or something similar as well.

Any other questions?
