Claiming and describing fake Christianity is antichristianity
"Anti" (Greek, in Latin "vicarius") means "another", substitute, or in place of.
Those who hate true Christianity because it doesn't allow or give one things it rebukes,
but who still seek all those things while also wanting the benefits of Christianity,
foolishly believe an adulterated Christianity is acceptable,
and good,
to God and Christ.
Such apostates are blasphemers.
