there are no people who are on the oppressed side of all power groupings. depending on your life including your vulnerabilities, but to SOME degree applicable to truly everyone, i want to see people caring about oppressions that target people who are not themself.

you certainly don't need to know about all oppressions. nobody actually can! and you certainly don't need to know about different ones equally. but add in some knowledge, care, and effort for the oppressions that don't hurt YOU. that's part of being human.
