Okay you can forward your complains to the HR of your company and they'll look into it that's thier job, If that doesn't work try talking to the managment in person, If all solutions don't work then your last resort would be looking for another job.
I don't think that your managment would do anything about it out of a complain in pprune.
Okay so you're not brit and I don't know what you are, But generally speaking, People would typically think of westerners as racists if they stumble across blasphemous posts like this topic, That was my point.
And I'm not refering to you here I'm refering to the thread starter.
