I know I'm mostly retarded, and I feel retarded for asking this... but Wasn't the jet fuel Ignited on impact... hence ya know... The massive explosion?

Let's just assume The entire narrative leading up to the Impact Is true. So two Boeing 757 and two Boeing 767 were used.

Forget about how the buildings collapsed. It was obviously controlled.

But why would anyone arguing against the narrative "Jet fuel weakened the steel" with anything other than-

"The explosion we saw... Was the fucking jet fuel. It's not like half of the fuel resulted in the explosion and the other half drained down the elevator shaft."

Please explain to me why I'm retarded for thinking there could be no jet fuel after the explosion... and anyone debating it's relevance after the explosion- Is NOT retarded.

Was the jet fuel Melting steel beams- Part of the psyop? Make everyone look retarded? People arguing it can't melt steel beams- As well as the people arguing it can? Like It's an irrelevant debate- Is it not?

Thank you to anyone who can answer this simple question with a simple answer...
