Seems to me to be an excellent post. apparently, DJ has received reports on a couple of speakers that harassed specific women, but for some reason does not deem them to be official reports. I don't know what to think about this. It seems DJ was even more wrong than I thought.
Here's the problem I see.
One, whatever policy is in place should be carried out and when available, data compiled. Although, in this situation, it appears the mere perception of danger overrides thinking, so it's a double edged sword - meaning no amount of data showing TAM to be safe will affect whether or not women feel it is safe.
Two, exactly what is 'harassment' exactly? There seems to be very wide range, from a joke on twitter to attempted rape? The inclusion of one seriously undercuts the seriousness of the other and makes any meaningful discussion impossible.
Three, the fact no amount of data and apparently regardless of the incident rates - women will feel unsafe does point to the fact certain people (not all) are fear-mongering. That is, overstating exceptions and presenting them as the rule, thereby scaring off other women.
As for fixes:
Make policy public, and make the implementation policy and reporting of incidences compulsory broadly, for women, for men, for speakers etc..
Create safer places that register with TAM to be in compliance with a specific code of conduct for patrons, servers etc and branded as such with staff on hand to effect rescues or ejections.
Don't hide the statistics. Make a report of it. Publish the data. Let people know what the real threats are. At the very least you remove a bullet - though this seems to be somewhat ineffectual.
Have a list of speakers who have harassed women. But also have a jury panel to look at the evidences. Have a trial or hand the information over to civic authorities. If a law is broken, have the infraction addressed.
Clearly define what harassment is and isn't.
