“But I shouldn’t have to” is a trap, everywhere it occurs. It cripples one’s ability to act on an emotional level, and manifests as all kinds of resistances and avoidances that ultimately prevent you from seeing the problem clearly - and if you somehow do see the problem clearly, you still don’t want to do anything about it.
The world owes you nothing. You exist. If you want love and fairness and a reasonable world, love and be fair and be reasonable, and choose to work together with those who are. Where you work, what you spend your time on, where you spend your money, and who you spend your time with are your places of impact. Don’t let others steal that - particularly over ‘but I shouldn’t have to defend myself.’
