There is an important distinction between structural sexism and individual sexism. And doing something that is sexist, racist, homophobic, you name it, is not necessarily tied to intent nor to consciously believing women/ethnic minorities/LGBTQ people are worth less than straight cis-male white guys.
Mansplaining is when a man does not realise that they don't know what they are talking about and just posit their own narrative as fact. It is a result of society's gender norms training them to do so. For men to be considered "real men", telling a compelling story with confidence is more important than bing correct - the scientifically appropriate level of self-doubt and "well this is what we know, here are my sources" is not "manly".
This is Toxic Masculinity in a nutshell: societal norms for what it means to be a "real man" that are detrimental to society and all genders - there are plenty of things that guys should do to prove they are "real men" that are detrimental to them too.
His answer and the societal norms that lead him to that thought process to post that answer, are an example of a toxic norm that most people aren't even consciously aware of. The sooner we acknowledge that and fix this, the sooner we are all liberated from structural sexism and toxic masculinity (and I do mean all - I feel very inhibited by toxic masculinity as a guy, and I think all men are).
Arush's answer is an example of mansplaining. The fact that it is about menstruation makes it even more ironic. That does not make him an asshole, nor someone who believes women are inferior to men - he acknowledges Saredin's answer as excellent. It just makes him unaware of all the structurally sexist norms that he subconsciously is bound to. And the same applies to the people who voted for his answers unaware.
Well, I guess I'm not a real man then. Thanks for your mansplanation!
Because if so, there is a - perfectly reasonable - misunderstanding of my intent here. Read what I wrote again, more closely: all it is describing is a societal norm that I would like to get rid of. If you think you don't act that way, great!
This is not an accusation, it would be a perfectly understandable response (I get defensive all the time when my GF points things out to me).
At no point am I talking about you, nor saying that you are "not a real man". At no point am I saying that you are a bad person if you do or do not act this way. I'm sorry that you feel defensive, but there really is no need to. I'm not accusing you, nor would I blame you or any man for having toxic masculine behaviours. It's not your fault to be raised in a society with those norms, after all.
If you have the time, please watch Why Are You So Angry? by Innuendo Studios[0]. It also goes into how societal norms about good and evil train us to think things are about us and personal attacks when they aren't (the video highlights gamergate, but the process is not gender specific).
But the short version is: people tend to get very defensive about topics like sustainability, feminism, racism, animal rights, etcetera, because it makes them question whether they are good people or not. But ultimately, that is a self-centered response. Whether or not one's actions make them a good person is ultimately less important than whether or not what they do is the right thing to do.

I had a similar experience when I refused to drink alcohol as a student: I don't mind others enjoying it, I just happen to not like it. Yet a lot of my friends in college felt like I was judging them.

I don't know WTF is Quora basing their raking on; apparently it's an algorithm that combines a bunch of factors: https://www.quora.com/How-does-the-ranking-of-answers-on-Quo...
Don't be sexist. Maybe it's because his answer is shorter and hers exceedlingly long? Or is it because people like analogies (even wrong ones) more than scientific references?
