Riot sexism analogy
This is the best way I can think to describe it is this:
You cook a burger, but you somehow overcook it to the point where it's smoking, it's charcoal, covered in carcinogens, and completely inedible. Knowing this, you still want to eat the burger. So you also eat a raw burger to "cancel it out", which obviously doesn't work. You eat one thing that will harm you, also eating another thing that will harm you will not help. The proper solution would be to throw out the overcooked burger and prepare and eat a properly cooked one.
Now let me translate this to Riot's situation. Riot's overcooked burger is the sexism against/under-representation of women in the company. Then what they do after that is eat a raw burger, AKA being sexist towards men, hence doing another thing to harm the company. What they should have done is thrown out the burnt burger, by giving a simple public apology about the treatment of women in their company, and made a proper burger, by simply being equal in the company and avoiding the new problem in the first place.
You can't just fight sexism with sexism. You fight sexism with equality.
