For me, it's when they use gaming to have thirsty people for attention or profit instead of legitimately enjoying gaming of any kind. This is especially apparent when we see female streamers that only play FIFA or Call of Duty, having webcames set up just to see their boobs and receiving over $1000 donations because of their looks. Few streamers and YouTubers actually provide content without having their looks controlling their channel, such as Ms5oooWatts, Laced Up Lauren, lolRenaynay, and so much more. Sure they're beautiful women, but that's not their focus; their focus is on the game that they're playing. A huge controversy covered this point with Smash Bros. Icon Sky Williams addressing this situation, but then blew up to a huge scale argument with other female streamers such as Kaceytron and previously mentioned lolRenaynay, being covered on websites such as Kotaku. Men have a prejudice outlook on women that play video games because we're unsure if they're saying that to gain attention rather than being dedicated gamers. Not to mention the countless controller selfies with women being almost being naked with a controller covering their tits all across Instagram, Facebook, generally any social media outlet has these people that do this.
