Because for all the crap people give America for conducting foreign policy according to its economic interests, everybody else does the same. And right now, doing business with China is lucrative because of their human misery arbitrage.

Because its impossible to say fuck allah in front of a muslim Eduated or not they are way too conformance to religion. I can the same to a christian or any other religion friends and joke about it and does not have to fear.

In politics, everything happens primarily to gain or maintain power. If some group of people is not relevant for either, people in power will not stick up for them.

Muslims are hardly a unified front. Look at how many majority-Muslim countries have had civil wars or wars against each other at some point in the last 30 years.

Because Muslim countries by and large are not in geopolitical or economic positions to act unilaterally in any way that is a)remotely effective, and b) not massively costly in economic and political terms.

The willingness to take a financial / trade hit for a random group of people hasn't been a common event as far as governments go... much ever?

Sad but that seems to be the case.

Everyone is utterly dependent on cheap Chinese manufacturing. The price of manufactured goods would probably quadruple overnight if companies had to abandon China.

It’s not just cheap labor. China has all of cheap labor, lax environmental laws, cheap energy, a very manufacturing friendly government, a tech ecosystem, local expertise, and infrastructure. It’s literally the ideal place to manufacture, at least from an amoral economic perspective. Nobody can compete with China in manufacturing except in niche high skill areas.
