TBH, I mostly just dislike it when people act like saying "all lives matter" discounts black lives.

Saying "save the ocean" doesn't mean "don't save the whales". It means "save the ocean including the whales".

I like being inclusive and I like being pedantic about language, using gender-neutral pronouns, and using "trunk" for the main git repository instead of "master". I should be able to include everyone without being associated with white supremacy.

And even on to "save the whales", sometimes that does lead to people disproportionately paying attention to the whales instead of the other creatures, though a better example would be "save the pandas". People often disproportionately pay attention to cute or interesting endangered animals like pandas or tigers, while ignoring saving other species that might be easier and more practical to save. The latter point about other species being easier/more practical to save has nothing to do with BLM/ALM, but the point is that sometimes paying attention to one part of the picture specifically, brings attention away from the full thing, paying attention to one animal instead of the entire ecosystem. We need to end discrimination and police brutality, and these don't only happen with black people. Perhaps we can start with the latter, as it seems to be the bigger issue lately and is easier to define, IMO.

PS: Despite somewhat disagreeing with the point, I'm still up-insightfuling your post anyway, as I do think it contributes to discussion in a site which is otherwise biased against BLM. Whichever community I am in, I like seeing the viewpoints which are underrepresented in it.
