does it really? it sounds like if their gender was omitted in the first place, the topic would not have been breached. i'm not saying their conclusion is incorrect, i'm just confused by how they got there.
say for example, a "gay computer scientist" did an AMA. some people would (rightfully) ask "why does your sexual orientation matter?". others will make fun of them for being gay.
the only thing i'm convinced of is that some people like to harass and provoke and troll. and for those people, minorities are easy targets. and the internet is the easiest and safest place to do it. and when you're dealing with an audience of 5000 people on Reddit, statistically speaking a subset of them are going to be that kind of stupid.
edit: the fact that my comment, and literally over half the other comments in this thread are grey, support my simpler conclusion that uncivil people exist.
