Also, you can be sure there's far less sexual harassment now than in the 1970s and 80s.
Well, women chose to get the fuck out. The hostile behavior experienced online would never be tolerated in a face to face setting.
Of course it's only a theory and I was too young to remember any first hand experience of the 1980s.
Perhaps some small porn BBSs or IRC channels had a different atmosphere, but the "tits or gtfo" mentality is mostly something which appeared over the last decade or so.
I have no doubt the BBS world was full of creeps, and that could have been very discouraging to someone getting into computing. My point was that behavior was far more segmented away from mainstream society than (say) Reddit.
