> but DO NOT UNDERESTIMATE ITS MALIGNANCY BECAUSE IT IS THE YOUNGEST!

Nobody does this
> as yes, all of the Abrahamic religions were founded by the wicked Semites

Why are they 'wicked'?
> All need to be destroyed by nuclear hellfire, with those people given no mercy. As I explain, it will make more sense why those Semites deserve no mercy.

This will never happen, you're better off just making peace with it if it bothers you so much.
> It is also dubbed the world's fastest growing religion, this narcissist sister's persuasive and forceful tactics of conversion is very effective.

Its growth is due to birth rates, not conversions. Isn't this obvious??
> Muslims left a trail of destruction and killing anywhere they went in all four directions

No they didn't, the conquered peoples remained non-Muslims and were therefore used as tax cattle. Their conversion was a long process and it hurt the Caliphates' treasuries.
> No other religions, customs, were allowed - except the ways of Allah - chaos and narcissism.

Judaism and Christianity were tolerated but not preferred.
> Islam and Christianity are haters of humanity conspiring to destroy the world.

24.1% of the world's population are Muslims, 31.1% are Christians. They ARE the world.
tl;dr You're dumb and this thread is the Dunning-Kruger effect in action, with genocidal fantasies sprinkled in.
