I recommend you read the Humanist Manifesto (I & II)...
First, see how it stacks up against the tenets of classic Marxism and the Communist Manifesto.
It's an "eye-opener" of a comparison...
Second --conduct an intellectually honest self-examination & check your own spiritual/moral convictions...
Especially concerning the "basic goodness of humankind"...
And the ultimate ability of mankind to affect his ultimate destiny...
In other words, the inferred expectations that mankind will somehow -- in the final analysis-- "save" themselves...
Have a great day...
