I could be misinterpreting but I don't think Angillion is of the opinion that you should have any doors closed to you based on your gender, if I'm understanding correctly what he does take issue with is the idea that a feminist is for equal rights for all (or if they are then they are suffering from a delusion is the general point).
Broadly speaking the argument would be if you're a feminist then your position is that females should have greater rights than they do now (often over and above what is extended to males) whereas if what you want is absolutely equal rights without any discrimination about the gender you are proposing a case for you'd be an egalitarian (or some other more suitable term if there should be one).
You're not misinterpreting. Although I think "suffering from a delusion" is a bit harsh. I wrote "conned", which isn't the same thing.
Also, it's not just about rights. It's about everything.
For example, healthcare. The feminist position is that more resources should be allocated to healthcare for women. That is not a radical feminist position - it's every feminist position.
Note that the question of what resources should be allocated to healthcare for men simply isn't considered. It's completely irrelevant within that framework whether women currently get 20% of the resources, 50% of the resources or 99% of the resources. It's simply about more for women, because that's what feminism is. More accurately, more for women who conform to what feminism says they should conform to - all biopolitical groups require at least some degree of conformity. The last time anyone bothered looking in the UK, healthcare spending on women was seven times as much as healthcare spending on men. All feminist campaigning on healthcare was still about more for women only. Which means less for men, as the amount of healthcare resources is finite, but that wasn't the point for the majority of feminists considering the issue because they simply don't consider men at all on a social/political scale. Perhaps on a personal scale, perhaps not, but not on a social/political scale.
To a person who advocates sexual equality, the correct allocation of resources would be on the basis of need, not on the basis of sex. That would probably result in the majority of healthcare spending going to women, but not 7 times as much and, far more importantly, because of need rather than sex.
