Women generally can't compete against men, especially at the highest levels. There may have been just 1 woman that could.
So if you get rid of woman titles and tournaments, you basically get rid of women.
However, I think it is fair for there to be men only, women only, and mixed tournaments.
Here is smtg that really bothers me. Why is there a title called WGM, like a specific category for women. And not only that, the rating you need to be a WGM is 2300 but for just normal GM its 2500. This kinda annoys me a bit, like they made the WGM rating lower just because they think women cant reach that high and honestly I think this isn't fair. This is just my opinion tho. Thx!
