To be perfectly fair, motorsport is one of the only sporting disciplines where it doesn't matter what you were born as, identify as, or what is between your legs. Once you're in the cockpit it's about how fast you can go, that's it. Sim racing levels the playing field even further by removing the physical stresses that in a few cases may hold back a woman from real life progression.
I think sim racing is as level a playing field as one could possibly envisage, and as such it should be segregation free. If someone is quicker than me (and many are), I will (like most) doff my cap, regardless of their race, sex, etc. None of that stuff is relevant.
