Yeah, I think this is fairly common. I'm pretty good at not being overly adversarial online, but that takes me a bunch of active effort. Sometimes that means taking a big breath and moving on.

I think it's admirable that you care about contributing through commenting; I saw a similar stat when I moved to Lemmy and I have also been more active in commenting. However, if you're not enjoying how you're typically engaging, perhaps a different framing could be useful: rather than (or in addition to) thinking about commenting as you contributing to the community/platform, think about it as something that you're doing to enrich yourself. For example, sometimes when I do get into spicier discussions, it's because I am responding to someone I disagree with, but whose points have caused me to think differently. Or maybe I am enjoying the practice in articulating my views on a complex matter. Or maybe it's cathartic. Thinking about what I hope to gain from a discussion helps me to avoid unproductive discussions where it's just mutual attacks.

If you can't find a middle way, it's also okay to not comment on things. My opinion is that we do owe a duty to the communities we inhabit, and in the online world, that might imply that it's good to be contributing via commenting. However, informational self-care is incredibly important nowadays, and it's so easy to become burnt out. It's okay to not engage in behaviours that cause you harm (or aren't encouraging you to grow in the way that you would prefer).
