My group was confronted with this way back right after we started playing OAD&D. I think the example is still relevant so I'll share it.
We'd been playing for a few weeks, when surprise surprise my older cousin decided she wanted to join the group. This was in part because her little brother insisted he play but she was also interested in playing after watching a session. The gaming group was made up of seven males and the rest of the group very much wanted her to play as she was smart, well spoken, cool and most important off all in their eyes - attractive.
She rolled up a fighter using Method 3 in OAD&D and ended up with an 18 in strength. She decided to play a human and rolled 18/95 exceptional strenght. However, being a group that played by the "rules", the books said human females were limited to 18/50 strength. I mentioned that, she didn't think that was fair to her as a player despite the fact men have greater upper body strength than women do.
So here we were with a very basic core rule getting in the way of a player enjoying the game. So on the spot being DM, I house ruled the male/female strength limits abolished and male or female PC's would use the male limits. Went forward and had fun.
This was in the early days of my fledgling Greyhawk campaign back in 1980. Greyhawk can treat women as second class citizens due to it's historic basis in medival Europe. In the interests of fun for the group my Greyhawk got ERA in year 0. Women had the same rights as men etc, sexism was present in some areas but not in many areas. So this became a core element in my version of Greyhawk.
Later a few of the male players complained they couldn't rape and pilliage with my cousin present. At this point, I was very happy she was an active player in the game because I didn't want my OAD&D campaign to go down the route so many other D&D games had went down. My PC Greyhawk stayed the way it was in the developed civilized areas. Another player argued about the strenght limits but did some reseach and discover the limits for human females were too low as 18/63 was female max at the time which is pretty darn strong in anyones book. At this point several in the group realized sometimes the world isn't exactly the way we might think it is.
While many DM's critized this aspect of my campaign back in the day. To my delight, in college there were several attractive females that were willing to play in this same Greyhawk campaign. Today this same campaign is still around and active with four females and six males.
Three of women that play in the group had strong reservations at first. However, when describing the campaign world where they would be adventures, I mentioned something about how women had equal rights under the law in civilized areas and used the same strenght limits as the males. I gave them the same campaign summary I'd been giving since 1980. Quickly they warmed up to playing and I learned later mentioning the way the campaign world worked regarding women had a lot to do with this. The ERA part as just another matter of fact part of the world was important to them.
I will say there were a few potential male players that couldn't deal with the idea and wouldn't play as a result. However, I think that was their loss, not mime or my campaigns. I think the reason my 1st ed OAD&D game is alive and well is the discovery that having fun meant adapting.
BTW - on another board discussion the female strength limits, I found examples thanks to the Olympics that 18/76 should be the current female strength limit if someone still insist on using them and 18/00 is still too high for max human male strength as 2004. ~18/95 is about right for the current human max.
