o .o Alright... so, will there ever be a time where a girl can play a game, online or not, without other male gamers goes "GASP! You're a girl??!!!" or "What are you doing here? Go back to kitchen and make me a sammich!" or something along that line?

Unless society or those communities regress and stagnate, yeah, eventually. Change tends to happen when the majority's opinion changes or enough people show their disagreement with traditional opinion/sentiment to create a stir and shake assumptions. Often, the people that want progress have to push for it.

It's already improved to some degree. The fact that people are more aware of it is part of that. 

Though there's always going to be discrimination against the traditionally powerless and favoritism for the traditionally powerful.
