Yes, it does suck for anyone who undergoes sexual harassment.
But you're using the word "typical". It connotes that such harassment is not only regular, but expected if a woman attends a conference. Nothing you've linked to (and nothing they've linked to from what I've read) supports the position that sexual harassment is activity that a woman should expect to be typical when going to these conferences.
Do they happen more than any of us would like? Most definitely. I agree it's a problem. I disagree that it's a typical problem.
