Just another thought about one of Bob's comments:

gatherings have less harassment, but higher report rates than most.
I thought about this and it makes a lot of sense. Personality tendencies could play a role here with women. Female atheists are plausibly more assertive, less conformist, and believers in gender equality. When they get harassed, they are then more likely
than female religious believers to feel,"This isn't right!" Female religious believers have more conventional attitudes about gender norms, such as "Boys will be boys" and take a purely defensive posture about male's sometimes predatory attitudes. Hence
Bob's observation about higher reporting.
