Is my argument against afterlife an equivocation fallacy?

[BrianSoddingBoru4]

You don't think anyone believes in an afterlife?  That's pretty much the basis for Christianity.

No, I think it is rare that somebody believes:
1. Afterlife is real.
2. Near-death experiences are not glimpses of an afterlife.
Other than that, there are some denominations of Christianity that don't believe in afterlife. Jehovah's Witnesses, for example. And it's hard to tell what the early Christians believed. The Gospels contain verses that appear to deny afterlife, saying things as "Nobody has yet been to heaven.".

How can it be rare that there is belief in an afterlife when it is common that NDEs are glimpses of an afterlife?

For the record, JWs do believe in an afterlife of sorts, it’s just kind of wonky.
