The most toxic game community

Tf2's community is still pretty toxic. Even high level players, and big names in the community are either known for being toxic, or have said some extremely incriminating things about other people.

I would also say speedrunning is pretty toxic. There are a lot of elitist dickheads, and although there are people who are extremely friendly, nice, and want to help others learn the speedrun, there's a lot of people who are the exact opposite.
