If you think that replacing a person with an object cannot be an artistic choice
Literally nobody is saying or thinking that. What we are saying is that there is absolutely no way that OP's prompt contained "...and make the optimist BE the glass itself...".
The irony is that you're giving OP way more benefit of the doubt in your reading of what they produced than you've given me, and instead argued against a complete strawman.
This is a lot of mental gymnastics going on here. Reading John 6:10 and Mark 12:13 as "Jesus wouldn't agree with Marx because Marx is of this world and Jesus is only about heaven" is a hell of a leap.
Your analysis would come off slightly less disingenuous if not for the fact that you're a very active poster in the conservative groups and not once have you raised any objection to the religious right being neck-deep in the running of the country. Seems like "don't co-opt Jesus to push your politics" only applies to leftists in your world.
