Muslims go way beyond Communists when it comes to brainwashing. Even
the rampaging mobs of Maoists during the Cultural Revolution did not
go around blowing up buses and airplanes, and certainly not
themselves.
Islam is similar to Communism in that both are thought viruses, also
known as 'mnemes.' Mnemes infect minds in the same way biological
viruses infect cells, replicating and brainwashing the host organism,
using the infected host to transmit the mneme to others. This is how
cults originate, and Islam is a perfect example of how mnemes work.
