Jerusalem and Israel were owned by other people before the Byzantine Christians. Same goes for Spain as well.
You are very inconsistent in what you consider "rightfully owned."
Also, you can stop being apologetic for the Inquisition. Jews weren't forcefully converting anyone and it was the Christians who forced them to convert or die. It was a catch-22, Jews were told to stop practicing their faith and convert to Christianity and any who were found not to have done so were punished.
For some reason I doubt that you defend Muslims who have forced everyone in their region to convert to Islam.
But the Christians did not take Israel or Spain from anyone, they were both under the Roman Empire which later converted to Christianity.
On the wikiepedia article on the Alhambra Decree(the expulsion of Jews from Spain), "The primary purpose was to eliminate their influence on Spain's large converso population and ensure they did not revert to Judaism." It was to prevent Jews who converted from reverting back. The Jews were given the option to convert or leave.
Christians were never more than a despised minority in Judea, just because your boy came from there doesn't mean the majority of Judeans ever folliwed his sect in the time the Romans had the run of the place.
But the Judeans were expelled from Judea after their treacherous rebellions against the Romans and Judea was renamed Palestine(the destruction of the Temple and defeat of Judea being foretold by Jesus). It was resettled by Romans who converted to Christianity when the Empire became Christian and then the Muslims invaded.
The Romans were an oppressive foreign regime, they were the ones that nailed your bloke to a tree remember?
Also Constantine made the Empire Christian in 306 AD, do you know how the acronym AD relates to Jesus? Anno Domini anyone, here-I'll make it easy for you. BC, before Christ.
Actually the Romans only crucified Christ because Pontius Pilate was forced to by an angry mob instigated by the Pharisees. Jesus said to "render unto Caesar."
And Jesus stood before the governor, and the governor asked him, saying: Art thou the king of the Jews? Jesus saith to him: Thou sayest it. [12] And when he was accused by the chief priests and ancients, he answered nothing. [13] Then Pilate saith to him: Dost not thou hear how great testimonies they allege against thee? [14] And he answered him to never a word; so that the governor wondered exceedingly. [15] Now upon the solemn day the governor was accustomed to release to the people one prisoner, whom they would.
[16] And he had then a notorious prisoner, that was called Barabbas. [17] They therefore being gathered together, Pilate said: Whom will you that I release to you, Barabbas, or Jesus that is called Christ? [18] For he knew that for envy they had delivered him. [19] And as he was sitting in the place of judgment, his wife sent to him, saying: Have thou nothing to do with that just man; for I have suffered many things this day in a dream because of him. [20] But the chief priests and ancients persuaded the people, that they should ask for Barabbas, and take Jesus away.
[21] And the governor answering, said to them: Whether will you of the two to be released unto you? But they said, Barabbas. [22] Pilate saith to them: What shall I do then with Jesus that is called Christ? They say all: Let him be crucified. [23] The governor said to them: Why, what evil hath he done? But they cried out the more, saying: Let him be crucified. [24] And Pilate seeing that he prevailed nothing, but that rather a tumult was made; taking water washed his hands before the people, saying: I am innocent of the blood of this just man; look you to it. [25] And the whole people answering, said: His blood be upon us and our children.
