Also, in the wars of conguest and reconquest, nobosy offered to restore the Holy Land to its original owners.”
Hmmmm, let's see. I guess you are referring to the Canaanites as they were living in Canaan when Joshua and the Israelites invaded the land, and it subsequently was divided up among the tribes of Israel. I doubt there would have been any need for a Crusade had the Jews (Israelites) been governing the Holy Land. The problem is Islam, not Christianity, Judaism, or any other religion outside of Islam.

If you say so. The Jews didn’t fare well under Christian Byzantine rule in their own land.

...Here is one eyewitness account of an attack on the Jewry of Mainz in May of 1096. This comes from The First Crusade by August Krey, and it is a letter written by a Jew who survived:
“The Jews of the city, knowing of the slaughter of their brethren fled in hope of safety to the Bishop of Ruthard. They put an infinite treasure in his guard and trust having much faith in his protection. He placed the Jews in a very spacious hall in his own house that they might remain safe and sound in a very secure and strong place.”
“But ... the band held council, and after sunrise attacked the Jews in the hall with arrows and lances, breaking down the bolts in the doors. They killed the Jews, about 700 in number who in vain resisted the force of an attack of so many thousands. They killed the women also and with their sword pierced tender children whatever age and sex...”
This is how about 30%-50% of the Jewish community of Europe met its end. Some 10,000 Jews of an estimated population of about 20,000-30,000 were slaughtered by Crusaders mobs.
