I get what you're saying. Although I find that referring to humanity as a collective, or using "we" as in "we are in this together" in discussions like these runs the risk of homogenising human societies into one, even though a large part of humanity's historical impacts on the environment has been heterogeneous (i.e., industrial revolution beginning in Western societies). You can find the same criticism surrounding the term "Anthropocene" in academic and general settings.

Countries such as Pakistan and Pacific island countries that have contributed the least to climate change are among the most impacted, which is why two questions (among many others) have loomed climate politics over the past 30 years: "Where does the liability fall?" (Ex: loss and damage fund) and "How can I, as a country, be in a better position within a global crisis?" (Ex: disagreement over the global warming potential of non-CO2 emissions due to different chosen time horizons between countries; GWP100 vs. GWP*; this greatly affects carbon accounting in agricultural countries that rely on cattle for instance)
