You do have to realize the difference between hula hooping and making out. Hula hooping isn't even a slightly sexual act. Furthermore, objectification is a huge issue in the lesbian community, so in both the hula hooping and making out scenario, gawking is not okay and contributes to an already sexist power structure.
The amount of tone-policing you've received for this comment absolutely floors me. My perception from this thread is that men can say whatever offensive thing they want about women, but as soon as someone says something that might be slightly harsh in defense, suddenly people care about the tone of the argument. Suddenly you're "attacking."
