As a black dude living in America, I strongly disagree. The sad truth is that there a lot of racists in this country. No, not all of them are wearing white sheets and burning crosses on front lawns, but there are plenty that makes it clear that this county doesn't want to progress past that racism. It goes beyond gaming, so I think that's a topic for another day, but the main reason why I avoid multiplayer games is because it's often filled with racism, sexism, homophobia, and a plethora of other hate speech. Personally, I have not the desire or patience to power through this shit anymore.
These people review bombing firewatch may be a small number, but the community that fosters this mindset is not. Obviously, it's not the entire gaming community, but it ultimately doesn't matter. For many minorities, women, and members of the LGBTQ community, gaming has been far from welcoming for them, even if it doesn't always devolve into hate speech.
