Many websites have rules regarding the content of discussions and comments, and here are mine:

Be professional and polite. If you disagree, that’s fine, but don’t include personal attacks.

Stick to the topic. This is not a forum where you can start your own discussion on something.

Don’t post anything that could be interpreted to be threatening, harassing, bullying, obscene, pornographic, sexist, racist or homophobic. No abusive language will be tolerated.

Try to substantiate your claims with facts - links will be permitted if they substantiate your point.

If you don’t follow these rules, your comments will be removed.
