This is a quote by Martin Niemöller, a German theologian who spent eight years in concentration camps towards the end of WW2 and who afterwards publicly spoke out a about the dangers of complacency in the face of fascism.
First they helped fund a literal genocide, and I did not speak out—
Because it wasn't my realtives being killed by US bombs and I was afraid that standing up and doing the right thing would have costs for me personally.
