With all the recent happenings/mentions in the past few years in regards of exposure of certain people in the community, the unfortunate experience that some players were victim to, and the overall "toxicity" (for this post, summing it up as the use of racist, sexist, homophobic slurs, and being a rude jerk) that has been around the community throughout all these years (and some of RGL bans of them), the need to pay attention to these issues and take action only becomes more critical for the community in my opinion.
Tagg is a great guy. I remember some of us playing Xonotic with him and he was having an enjoyable time as we all were, he's a genuinely cool dude from my perspective and it's truly sad he had to go through what he went through in his video (aside from the TF2 weapon balancing). For as long as I could remember and as well as all the other old TF2ers, toxicity has always been around for years and will continue in TF2 or other games. Back then people were "tolerant" of it while not being toxic themselves and there are still many today that are like that. That doesn't mean toxicity is okay though in the end. Yes, it does happen in games like LoL, CSGO, or any other game, but those games also have large playerbases/communities and if they lost players because of toxicity, they'll still always have many players. For the TF2 competitive community specifically, we're not as "huge" as those other games and in my opinion every player counts. It's also especially easy to lose new players that are just trying out comp TF2 if they encounter "toxic" players in their first few games and they start to quit because of it. Same goes for long time players that eventually get tired of it. And if anything, this video from Tagg may unfortunately discourage some players from trying or considering competitive TF2.
As mentioned before and despite all that has been happening in the community, the question still stands, will anything get done about this? Or just like all the other videos/threads/happenings from what the community now knows, will it just be ignored until the next thread? As for what can possibly be done about this, I'm sure people could think of all sorts of ways to work towards making the community a less negative experience. While many are opposed to RGL, they have already taken the initiative a bit in an attempt to try to show that this negative behavior isn't okay. Forum moderators could start cracking down more on certain posts/people. Players could start being less of a jerk and the nice/tolerant ones can start to speak up against those that are being toxic.
Also, a shoutout to all of the nice players/contributors who happen to be reading this that have stayed all this time, put up with the bullshit, and maintaining a more positive experience for the game and other/newer players. While competitive TF2 is a great attraction in terms of ruleset, it's people like you that really make it far more enjoyable and worth staying, and this community would be utterly worse without you guys. Thank you for being awesome.
