Obviously not because as long as people are assholes, which will be for the forseeable future in my opinion, no one will be treated equally online. I think he's saying that there's no hiding form the assholes, if they want to be online and be making fun of people because that makes them feel high and mighty then they don't give a shit what your gender is, they just care about what they can tease you about. Because they're petty assholes.
But that asshole is far more likely to start shit with a girl rather than a guy. And there are way worse things to call a woman than a straight male.
So while all people do get shit, women get it exponentially more, and that asshole is going to go off, and continue to go off, far more constantly around the other sex.
In addition to that, you assume that only petty, angry assholes exists. It's a whole spectrum of shitheads, from perverts, nice guys, thirsty dudes, and sexists pigs. They don't have to be angry at their lives to be those things.
in this case, im going to say "really"
It's COD, puerile shitheads talk like that in games. Sure, they tailored the comments to her being a woman, but i've heard and been called everything imaginable back before i got into the habit of plugging in the headset and leaving it on my lap with my mic muted. It's the only way to play those games
This mentality of "it's always been this way, deal with it" and "me too!" isn't helping. She shouldn't have to mute the mic, and the vitriol spewed at you is nowhere near as much as a it is towards a woman.
