"how dare you talk about <literally any issue> when <major world event> is happening"

things do not stop being important when another thing becomes more important.

furthermore, there is a limit to how much energy I can spend on any given issue and how much of my effort will make a meaningful difference.

and on top of that, our societal problems are all interconnected. progress on things other than your own pet issue does in fact matter, and will indirectly make things better on the fronts you care about
