Muslims should do the opposite of what Jews and Christians do!

Bukhari: Volume 7, Book 72, Number 786:
Narrated Abu Huraira :
The Prophet said, "Jews and Christians do not dye their hair so you should do the opposite of what they do. "

In this hadith, it is obvious that any Muslim who does not dye their hair is clearly an apostate to their faith. After all, Mohammad CLEARLY commanded Muslims to dye their hair.

However, if one argues that dying the hair is an example of what Christians and Jews dont do, and Muslims should do the complete opposite, does that apply to all facets of life?

For example, if Christians and Jews use logic, does this mean Muslims should not use logic? Could this be a reason why the Israelis are doing so well economically and the surrounding Muslim countries, surrounded by a plethora of natural resources are doing so poorly?

Could this be the reason why the Middle East has not come up with any new inventions, since the dawn of Islam, and that the doctrine of Islam has subjugated Middle Eastern people, once the epicenter of science and innovation, to a vapid state of mental inferiority, where its governments blame their misfortunes on anyone else but themselves?

As to why Bukhari included this hadith, once can only guess... As well, since Mohammad clearly did not know every Christian and Jew, which Christian or Jew was he talking about?

If some Christians and Jews dyed their hair, and others did not, what should Muslims do?

Did Mohammad think that dying hair was a religious thing? What purpose would that serve if it was relgious? What purpose would it serve by doing something opposite of what Christians and Jews did? Is this an implicit statement that Mohammad hated Christians and Jews, stemming from the fact they were more logical than he was, and stemming from the fact that ultimately, it was the Jews who sold Mohammad bible stories that Mohammad plagiarized in his Quran?

Ishaq:264 "Allah revealed concerning Finhas and the other rabbis: 'Allah issued orders to those who had received the Book [Torah]: 'You are to make it clear to men and not conceal it, yet they cast the Torah behind their backs and sold it for a small price. Wretched was their exchange. They will therefore receive a painful punishment.'"
