I see these comments in society a lot. If someone doesn't agree with you they are automatically inclined to be your enemy, and reply with their opinion on the subject; which is one of the biggest issues for flaming and insults on the Internet. The mods/Bungie can't do much to stop this, they aren't here to babysit every member and to make sure no one gets offended. Even if we had a small army of mods we couldn't do that. The only thing that you can do to these "offensive" comments would be to report them.
