If (For Some Reason) You Find Atheists “Delusional”…
If you’re willing to dismiss someone as “delusional” based on one simple (and harmless) belief of theirs (like being an atheist) … that’s a little weird.
But what I really think is you’re looking for some “snap back” … someone to call you delusional or some other name etc. Maybe some “back and forth” about whether God exists.
Nope. Because get this…
If you believe in God, that’s your way of sorting out the World we live in. That is something every person on this planet is trying to do.
I think it would be wrong to use your religion as an excuse to harm people (in any way), or to try and impose it on others. Other than that … enjoy your short time on our planet.
We only have 75 or so trips around the Sun … what else are you doing with yours?
