Do not make personal attacks anywhere in Wikipedia. Comment on content, not on the contributor. Personal attacks will not help you make a point; they hurt the Wikipedia community and deter users from helping to create a good encyclopedia.

There is no bright-line rule about what constitutes a personal attack as opposed to constructive discussion, but some types of comments are never acceptable:

• Racial, sexual, homophobic, ageist, religious, political, ethnic, or other epithets (such as against people with disabilities) directed against another contributor. Disagreement over what constitutes a religion, race, sexual preference, or ethnicity is not a legitimate excuse.
• Using someone's affiliations as a means of dismissing or discrediting their views—regardless of whether said affiliations are mainstream.

• Pointing out an editor's relevant conflict of interest is not a personal attack.

• Linking to external attacks, harassment, or other material, for the purpose of attacking another editor.
• Threats, including:

• Threats of legal action
• Threats of violence or other off-wiki action (particularly death threats)
• Threats of vandalism to userpages or talk pages.
• Threats or actions which deliberately expose other Wikipedia editors to political, religious or other persecution by government, their employer or any others. Violations of this sort may result in a block for an extended period of time, which may be applied immediately by any administrator upon discovery. Admins applying such sanctions should confidentially notify the members of the Arbitration Committee of what they have done and why.

These examples are not exclusive. Insulting or disparaging an editor is a personal attack regardless of the manner in which it is done. When in doubt, comment on the article's content without referring to its contributor at all.

The prohibition against personal attacks applies equally to all Wikipedians. It is as unacceptable to attack a user with a history of foolish or boorish behavior, or even one who has been subject to disciplinary action by the Arbitration Committee, as it is to attack any other user. Wikipedia encourages a positive online community: people make mistakes, but they are encouraged to learn from them and change their ways. Personal attacks are contrary to this spirit and damaging to the work of building an encyclopedia.
