Two points:

1. Top-level sports isn’t fair. Most famous athletes are outliers in terms of height, weight, muscle mass, etc. Some, like Phelps, have genetic or developmental differences that give them a pretty significant advantage.

2. I must admit that the legal definition of ‘transwoman’ varies from country to country. In India, where I live, a person can legally change their gender without any medical intervention, and such people might have a physical advantage over cis-women. But in the vast majority of countries, they have to take hormones and / or do surgical procedures that reshape their body to be more ‘feminine’. Once they do that, they have no significant advantage over cis-women.

It’s memes all the way down.

If you want power over another country, attacking them is a very inefficient path. You will take losses, and you won’t be able to take their resources intact. The easier and cheaper method is to just bribe their leaders into selling you whatever you want.

The US starts wars even when it doesn’t need to, because there are a handful of companies that stand to make a lot of money selling weapons. No other country has such a large and influential military lobby, so other countries tend not to start wars for private profit.

The new guy won despite winning <5% of votes in the last election. If people vote for the candidate they like instead of trying to game the system by calculating who they’d rather not win the most, then maybe we can kick out corrupt incumbents and get in fresh faces (they’ll get corrupted over time too, at which point you rinse and repeat).
