But that is exactly the point you were making: that it would somehow be reasonable to "feel threatened" when 2 gay guys are having a sexual conversation within hearing range of you. You in fact agree with everyone else that this is not a threatening situation. Given that, what does this have to do with the incident at Pycon? Your argument is heteronormative at best because it also assumes that only straight men could every be offended by gay sexual conversation.
