Unfortunately, racist outbursts on public transportation aren't uncommon. Thankfully, there are courageous individuals who stand up to the aggressors.

A man in Australia, Nicholas John, took to Facebook to share a story about an exchange he says he witnessed between an Opal ticket officer (who he dubbed "Opal Lady") and a racist passenger during his train journey.

So, the story goes: the ticket officer came across an Argentinian passenger who accidentally purchased the wrong ticket. A nearby passenger rudely interrupted them saying, "Fine him, love. Fucking foreigners."

Opal Lady was having none of it. She left and came back with officers who escorted the racist man off the train. When he asked on what grounds he was being removed, Opal lady calmly responded with the c-word.

Boom.

The Facebook post went viral, with many people hailing Opal Lady as a hero.

Faith in humanity restored.
