The first sentence of the second paragraph is
- out of topic
- biased
- depicting categories of population as victims

When something is depicted as self-evident (or well documented, or accepted as certain, etc…), it is usually for lack of ability to deliver proof. There are only two exceptions to this:
- “Cogito, ergo sum” – Rene Descartes, founder of rationalism
- “We hold these truths to be self-evident” – US declaration of Independence

Other instances of self-evidence without logical proof behind them invariably hide judgemental statements… most of the time implying serious political statements. And don’t get me started on guns in the US…
I’d just say: beware those statements, they undermine credibility with discerning people.

Nonetheless, I do agree with your main point of conflict between sports and the tchador (muslim veil)…
