A couple of days ago the Quba Islamic Institute in Houston burned down. It's believed it was the victim of an arson attack.
Here's a little exchange in the comments to this post that's subsequently gone viral.
It was far from the only bit of internet hate the centre received.
Crystal Beach Fire and Rescue has denied that the man in the Daily Kos story is a member of the department. In a statement posted to its website, the service said:
"There have been recent post on social media from someone stating they are a member of our Fire Department and post hate messages against the Islamic Community.
Please know that this person, Dustin Herron, is not a member of the Crystal Beach Volunteer Fire Dept; nor has he ever been a member of our fire department. Mr Herron has posted on numerous social media sites that is a member of our fire department.
We are in the process of trying to track down Mr. Herron regarding the comments he made. We have also notified the Galveston County Sheriff Dept. regarding Mr Herron falsely stating he is a fire fighter within our organization.
We have received many e-mails regarding his recent social media post and comments. Please know that our Volunteer's give 100% effort 100% of the time."
