I think it really depends on where on SL you are and where in RL you are to be honest. I've lived in different cities across the world both in SL and RL, each one is different. I sometimes notice that SL is a predominantly female world- but in RL still male.
I've lived in places both RL and SL where you get no harrassment- or you can't walk to the shop without it. It's the same in that way- but in terms of the fact that RL women are oppressed because of their reproductive systems and physical strength, no- it's not the same. It's really not.
