That, he says, is the statement of what a utopia looks like. The sign emits vibes of hope for the future and the kind of world which would be perfect. It is what religions talk of and promote as a reason for support.
This utopia, however, does not come from a god. It is a utopia that can be reached here on earth and in good time. Instead of using a god to reach it, humans can reach it by themselves by believing in humanism. From this the link author concludes humanism is another for of religion.
Humanists believe in the ability of humans to successfully deal with whatever they face without resorting to a spiritual being. Christians often say, “Atheists don’t believe in anything.” Then, when humanists make it known they believe in humans the accusation is humanism is a religion.
I don’t see why being optimistic about the future means one is religious.
