[Serious] Atheist Dogma

[The Architect Of Fate]

Humanism can be religious, and there is such a thing as religious humanism, just as there simply is such a thing as christian humanism.

Don't take my word for it.  I know you have the internet.  Google.

The first humanists™ - the people who defined the position..weren't trying to do shit for atheists.  They were theists.  I can't even grasp at whatever problem you're arguing against with the idea that these are "erroneous definitions" - as if that were even a thing.  Definitions are axiomatic.  They literally can't be wrong.  If you're talking about some other thing, or concerned about some other thing..that doesn't mean that a definition is erroneous, it just means that you're talking about some other thing.

I'm willing to bet that whatever that is also already has a definition.

Indeed 

Christian humanism regards humanist principles like universal human dignity, individual freedom and the importance of happiness as essential and principal components of the teachings of Jesus. It emerged during the Renaissance with strong roots in the patristic period.

Historically, major forces shaping the development of Christian humanism was the Christian doctrine that God, in the person of Jesus, became human in order to redeem humanity, and the further injunction for the participating human collective (the church) to act out the life of Christ.[1] Many of these ideas had emerged among the patristics, and would develop into Christian humanism in the late 15th century, through which the ideals of "common humanity, universal reason, freedom, personhood, human rights, human emancipation and progress, and indeed the very notion of secularity (describing the present saeculum preserved by God until Christ’s return) are literally unthinkable without their Christian humanistic roots."[2][3][4] Though there is a common association of humanism with agnosticism and atheism in popular culture, this association developed in the 20th century and non-humanistic forms of agnosticism and atheism have long existed.[5
