Nuns With Guns.

[Grace]

There's nuns with guns, they're ready to fight,
Fight till we all see the light,
They'll fight for the right for priests and their chums
To help themselves to choirboy's bums.
There's nuns with guns, they're standing tall,
Until they've brought God's love to us all.
They'll fight for the right for an unwed mother
To have her kid ripped away and given to another.
There's nuns with guns, they're ready for war.
God's the one they're fighting for.
They'll fight for the right for all those gays,
To get stoned to death for their unnatural ways.
There's nuns with guns, they're ready for action,
Killing the sinners the main attraction.
They'll fight for the right for the poor to be poor,
So they get to heaven when they reach deaths door.
There's nuns with guns, they're itching to fight,
Cos they are convinced that they are right.
They'll fight for the right for a Moslem to die,
Because they think their religion is based on a lie.
There's nuns with gun, they hate everyone,
They hate everyone who's having fun
They'll fight for the right for us to be miserable as well,
So we can avoid their made up hell.
There's nuns with guns, but the guns ain't loaded,
Now that religion has become outmoded.
They'll fight for the right to be stuck in the past
Cos they know that religion just wont last.

Hi, to be honest, this reads like a poem that's mocking another poem (a serious one)  about nuns with guns.
The mocking element, combined with shocking images, on a loop, may cause a reader to zone out, because it starts getting "samey" after the second repeat.  HOWEVER..you've got the makings of a good poem here..
A suggestion might be to put in metre and make it sing like a hymn in a catholic school. ("Fight the good fight with all thy might"..)  which would give it an ominous undertone. .
