@wren what you did was community defense. We need lots of people like you standing up for their neighbors in exactly this way.
You're brave, you're kind, and it's ok to cry and be scared. The important part is you did what needed to be done.
If anyone out there wants to be more prepared for this situation in the future, some organizations offer bystander trainings that prepare folks to respond to incidents of racism, sexism, or transphobia.
