I see the light. I see that lovely red beacon

So people are following another flag touting freedom for all. Where have I heard that before?

The Red in the US Flag - Blood shed to promote freedom for others.
The Red in the China, USSR, and Nazi Flag - Blood of others shed to promote power of the state.

Syndicalist red flag: The strength and blood of the workers

You might want to be careful

pretty sure it's red because of the bloodshed

It's red because it represents the blood, passion, and strength of workers

I knew about the blood, I just thought it was the blood spilled by the women and children of the bourgeoisie. And the proletariat for that matter.
