Why are other religions would not even bother to understand

Like i was preachin in a game (Where you can fight and build. i and someone else build the church)

and theres one Muslim guy said after the mass i peformed and there we like half of se

"Then why would he allow sickness" i said "He didnt, we allowed it to enter, because of original sin" HE SAID "Original sin? whats that a fake sin? " "it was with us since birth because of adam and eve" HE HAVE THE NERVE TO SAY "So babies died in the womb get to hell because they didnt repent? " "He knows justice, he wont send baby to hell" AND HE SAID "So called " Died for our sins" wow what a sham religion"

THIS GOES AROUND 3 HOURS I COUNTER BACK WITH LOGICAL STUFF LIKE "Jesus died for our sins and we can accept him with our free Will" "Then why people are sinning then" "KEYWORD: FREE WILL" "What a sham" he said

AND finally i said "well if you keep questioning our religion then how about i question yours? "

I started with the ways on they fight, their ways and Prophet Mohammed and HE HAD ANOTHER NERVES TO SAY "blah blah blah blah, "Ohhhhh~ forgive me fatherr for i have say a bathsheba outside" Yeah your prophet killed a man" LIKE HE DIDNT SUFFER THE CONSEQUENCES AND HE REPENTED UNLINE YOURS AND HE WASNT A PROPHET ITS KING DAVID. K-I-N-G D-A-V-I-D. He said "Then why are your popular people like trump is Christisn but evil" i explained luke warm AND HE WAS BEING SARCASTIC AND SAID "Wow give him a blanket to be cleaned, oh wait you christans cant be clean lazy and you need someone else to do it"

AND IT WAS 2AM IN THE MORNING AND HE STILL WANT TO ARGUE ABOUT THIS "sham religion" EVEN THO THE TEACHINGS IS TO LOVE, CARE, BEAR FRUIT AND BE WITH CHRIST WHILE THEIRS DO THE OPPOSITE

LIKE HE ARGUED ABOUT THE PROPHET, and before i leave he said THIS WITH A MOCKING TONE "our religion prays more thats why its real, unclean people touches the bible to be clean our quran you need to be cleaned" yes i accept other people's religion but not their way "I will rosary now, i will leave thank you" "Rosary in roblox🤣🤣🤣"

and thats where i almost snapped and tell everything wrong in their religion, prophets, ways in good detail that he cannot counter

and so called "Nicest religion" by them
