You say that as though male-male, female-female, male-female, and female-male interactions are all identical; they're not. I really don't think that she's saying she's going to indiscriminately grope people based on "whether or not she feels they're on hugging terms".

As far as a double-standard goes, it's a fact of (Western) life that a man going around offering unwanted hugs to women is seen as significantly creepier than a woman who offers an unwanted hug.

You're more than welcome to try to change that! Next time you receive an unwanted hug from a woman at a tech conference, make as much of a fuss as you want about it. Report it to the conference organizers.
