Nothing wrong with using goodbye. Words meanings change all the time.

Even as an Atheist, I have no problem with "merry Christmas" or "holiday". Why would I avoid "goodbye"?

When in parting, I usually tell people to "Have a great day."

I also say it to my cheese, as I grate it over my food, but with a different spelling: "Have a grate day."

I think 450 years is a long enough gap to safely use the word goodbye without anyone thinking we are “closet” Christians.!

Interesting discussion, but can’t we just ge back to eating babies?

"As Agnostics, we had best stop using that word ...." (sic)

Wouldn't the agnostic be unable to decide one way or t'other?

So long
See ya tomorrow
Have a nice day.

Many other options.. Bye ☺

God, in the Scandinavian tongues, from which the English word "good" originates, simply means good, as opposed to bad.
Hence, etymologically, goodbye is a contraction of "good things be with ye".

I see it rather as: a 'bye' is a temporary leave of absence, or a pause. So it's like, "In the interval of time we are apart, I hope everything goes well."
I don't CARE if there's an alternative derivation.

Every time a Christian mentions "Saturday" they are unknowingly paying homage to the pagan god Saturn, who ate his sons, thereby sanctioning murder, cannibalism and child abuse and condemning their souls to an eternity in Hades.

OK. In the KJV bible Paul said "I wanted to come to you but I was let." Language changes over time. The word "let" actually meant prevented at the time of this translation.

Maybe we should depart saying...."Take It Slow"

Meanings change: case in point - gay

The Bible talks about eating. As a result in protest I am never eating again. I will ahow those theist!

Ahoy.

Hoy.

That's okay, I say, "later tator".

Nah.
I'll argue the point if someone feels truly compelled.

Never knew that. From now on I will say "See you later" Whenever someone sneezes I NEVER say "god bless you" I always say "Gasientite" Note- I can't spell for shit.

The term "good" has grown well beyond its etymological origins. I have a knee-jerk reaction to anything that limits my expression.
I don't think this behavior would strip me of my agnostic cred.
