"Entourage" star Adrian Grenier for the tribute he posted on social media on Friday, September 11.

In the now-deleted Instagram post, Grenier wrote, "R.I.P. the 2,996 Americans who died in 9/11. R.I.P. the 1,455,590 innocent Iraqis who died during the U.S. invasion for something they didn't do."

This struck some readers as "disrespectful" and "classless," although others agreed with his sentiment and debated attackers in the comments. Grenier deleted the original post -- keeping up his other, less controversial 9/11 tributes -- which upset some of the people who respected his defense of the innocent Iraqis and did nothing to stop the people who were already outraged.

For example, here are some comments -- posted with another photo -- that seem to be about the deleted image:

bless you, but your spineless liberal ass then deleted it because you have NO BALLS!! Hahaha. You disrespectful fuck, you should move to Iraq and make movies there, I bet they would support you or atleast cut your head off on live TV

Your a faggot that deserves to die in hell

Another Career ended. I will not support anything that you are involved with. Your career just took a turn like the Dixie Chicks straight to the toilet.

YOU SUCK

Thank you for what you said. Sad there's so much hate shows how sensitive not just 9/11 but also how sensitive people are to the Iraq war. If it wasn't for the Iraq war a lot of things would have been prevented including Isis, their creators met in Americans prison. They were marginalized and radicalized in under the U.S.

Wow. Well, at least it's sparking a debate. Extreme reactions, like these, can cause a chilling effect where people no longer share their opinions, which is kinda sad when this country is all about free speech. But free speech goes both ways, and at least Grenier got a few people to exercise that right on an important day.
