Of course it isn't fair. People expecting this to be fixed out of fairness are the biggest thing holding back fixing the problem. It wont be. The people pushing this stuff are not interested in fair. At all. When that finally sinks in that women aren't going to appease their way out of this situation, there might finally be the actual action taken needed to reverse all this.
No woman should agree to compete against men in competitive women's sports. If women as a group stopped doing so, this would end within the month.
The vast majority of people around the world are on women's side in this. Even my Leftie friends say things like "I support trans people but they shouldn't be allowed to compete with other women."
The people and organisations which push this stuff will NOT change their minds. Nobody is going to say "oh you're right it isn't fair, I'll stop being a narcissist who will steal 35k from a woman who has trained most of her life for this."
This stops when woman as a group say "No" and until they do so it will continue. "Fair", "should", "shouldn't", "people will realise..." - none of these change anything. You can hope they will, you can want them to with all your heart. They do not.
If women don't want to compete against men then they must stop competing against men. Not wanting to do something and continuing to do it, does not stop that thing from happening.
