Lol, personally I love the console wars and the gloating back and forth. It's general all in good fun or at least in fun spite. Like I've been having a lot of fun laughing at overly defensive PS fanboys or the stupidity of the Xbox naming scheme, just like I did back in 2013, just switching out PS with Xbox fanboys. Xbox fans are a minority here as well, so as the underdogs it's understandable the few times they get to gloat, that they do so. Them gloating because of good Xbox news is not toxic in my opinion. What is toxic is people not playing around, but being deeply invested in console wars in a way that's not just fun ribbing. As in people suddenly caring about winning the sales numbers and not what they as consumers actually get. As toxic as that is, it should still be allowed.
What really annoys me is people whining about others "destroying their hype" whenever this next generation is put under a critical view. Like we're all part of a marketing machine or something and we need to entertain the circus. Personally I'm disappointed with both console makers and have decided to wait to buy a console. With everything being cross-gen for a couple of years, I imagine that like with PS4, the console will really get good after yeard 2 or so.
Don't really see what mods really could or should do. This is part of the season, been so every generation. If you're just looking to make yourself feel better you could stick to marketing material. This rollercoaster ride is a mix of up and downs, but it is without doubt at least exciting.
Trying to overly moderate is kinda what we want to avoid, outside of really clear cases of antagonism and not "x console fans gloating due to big recent news".
