All over the world sports are taking a stand against things like exploitation and war crimes. But not chess.com. I expect it is because they have a large user base in the said countries
This is where you are wrong. There isn't any factual corelation between chess and politics.
You can't respect or disrespect any international law by just playing chess.
This site is apolitical for the same reason, why any school should be apolitical.
Knowledge of given things isn't and never should be conditioned by any political opinion.
This is obviously subjective. The game of chess itself isn't necessarily political. It's two people moving pieces on a board.
But there are probably a lot of people who see correlations between chess and politics. Any time you have people (which play chess) and conflict (which chess is a game of) there will be politics of some kind.
If you type in "is chess a political game" in some search engine you will probably get mostly yes answers.
Politics is defined as:
"activities aimed at improving someone's status or increasing power within an organization"
Your chess rating, winning chess games etc.. gives you zero power and arguably only very little social status in compare to other skills..
A bad definition. Almost useless.
Define bad definition.
One which I couldn't accept, even after attempted persuasion.
Or: One which is incorrect.
The idea of making access to this site dependent on one's nationality is ridiculous. Playing chess is not a political act. Get real.
