<human>: Could you distill the essence of the text into 1-3 sentences?

One my my best friends forwards me 2-3 conservative and often blatantly false emails a week. Many are offensive, but I find it entertaining in a general sense.

They're often politically based--"CAN YOU BELIVE OBAMA BIN LADIN DID THIS LOL!!"

Today's email, however was a variant of this [one] A smattering of anti-Muslim comments allegedly made by Australian officials, that essentially told Muslims to assimilate or "get out of Australia."

I find religious intolerance particularly bothersome, so I responded with the following:
> Wow dude, that's about the most un-American pile of shit you've ever sent me. Please don't forward me ignorant crap like that.

To which he has not responded.

My question is this: **do I apologize for responding in that way?** I realize now I should have just deleted it and moved on like all the others, but this one struck a particular nerve.
<bot>: I told a good friend to buzz off over an anti-Muslim email. How do I avoid any further awkwardness?
