You are suggesting that the racism that people of colour suffer is nuanced to their origins? And that a differential in the level of single-parent families is the key. If this were true all that would be required to solve the problem is a substantial investment in education. Whilst the investment is very necessary and it would be welcome I do not think it is a simple as that.

Think that you will find if you speak to people that come from the groups you have identified as successful that they have experienced an equal amount of racism in their lives.

Also the Chinese are amongst the least religious people on the planet.

It's fairly obvious that no reasonable person wants racism, however, no reasonable person thinks that the media and football campaign against racism is anything more than self-serving virtue signalling.

There will never be zero prejudice against anyone or anything. This is just another out of reach holy grail held up to distract people from reality.
The trouble is that every generation is full of more gullible people to manipulate.
The law does not allow for prejudice, and that's the best outcome that any minority can hope for. The war is over, but it is in the interests of corporations and politicians to keep the fight going anyway.

Religion is not the key factor. It is a structured, stable background that encourages positive behaviour.

Structure is perhaps a rather clumsy word. More an upbringing that promotes a framework of personal discipline and morality which complements society.
In other words, one that keeps you on the straight and narrow rather than getting into undesirable pursuits.

Good parenting and a positive environment.

Yup but a one off is no good it needs to be weekly or a complete withdrawal. I never even noticed it this one how many other people missed it including the social media companies.

It's not just social media players need to go after UEFA and FIFA and their shameless pathetic small fines for whole stadiums abusing players.

Hit em where it hurts, threaten to withdraw from the champions league and international matches. I doubt they will because that means the players will suffer as well.

Well if you want to be taken seriously you have to have skin in the game.

One more point

It's a hall of mirrors, as it's always 'someone else' who is virtual signalling, and the person pointing it out who is inferring that they instead hold a genuine moral standard. In essence it's no difference from the type of behaviour it seeks to criticise.
