We can add OVFF’s anti-harassment policy to the list of ones that address the actual problem in simple terms, without any bans on causing embarrassment or prohibitions on discrimination in personal choices:
Harassment of any kind is not tolerated. If someone tells you “no” or asks you to leave them alone, your business with them is done.
Your right not to be harassed is not a right not to be offended. All of us have different things that we find offensive. If you are offended, the best solution may be for you to walk away from the person who offends you. Should that person pursue you and continue to offend you, that could be harassment.
There are probably a lot more good harassment policies than bad ones among science fiction, fantasy, and filk conventions. The ones that have good policies are just trying to solve a problem and don’t make a lot of noise about it. Those who want to control people’s behavior, speech, and thoughts in detail like to brag about it, so we hear more about them.
