Darwinism has been on the world's agenda for 150 years. Darwinist views were the biggest foundations of atheists, naturalists, materialists and evolutionists. These groups of people had difficulty supporting their views before. Not only them, but when Britain and other colonial governments used Darwin's proposition "only the fittest can survive" as a means to justify and legitimize their own colonialism, they were giving the subliminal message of "we carry out what's in natural laws because we are strong".
