A thought that's been percolating in my brain since I read Huey P. Newton's bio is that revolutionary suicide isn't truly death.
In reactionary suicide, you disappear. In revolutionary suicide, you live on in the struggle forever. People don't forget Huey or Che or anyone that dies for us. They live on forever in the minds and hearts of the People.
To die for the struggle is the only way a materialist can achieve the afterlife. Or something.
