Would they worship a chair?

Sorry to burst this bubble, but Catholics, (and I assume at least some Anglicans) do not hold that there would be "half the Eucharist". 
They believe that they get "body and blood, soul and divinity" even if they receive communion under one form. 
(It would be interesting to have them defend the "soul part", as in general they don't talk about the second person in their Trinity having a "soul").

I paid attention in Catechism class.   Of course, you could go to Catholic Answers and ask the question, (LOL).
It's also interesting that their deity seems to be required to accept the nature of (their) reality with respect to what constitutes redemption.

Does one receive the whole Christ if one receives Holy Communion under a single form?

Yes. Christ Jesus, our Lord and Savior, is wholly present under the appearance either of bread or of wine in the Eucharist. Furthermore, Christ is wholly present in any fragment of the consecrated Host or in any drop of the Precious Blood. Nevertheless, it is especially fitting to receive Christ in both forms during the celebration of the Eucharist. This allows the Eucharist to appear more perfectly as a banquet, a banquet that is a foretaste of the banquet that will be celebrated with Christ at the end of time when the Kingdom of God is established in its fullness (cf. Eucharisticum Mysterium, no. 32).

Still, don't you think that Christians are inhumane towards Jesus? Shouldn't Christians already make Jesus climb down from the cross and go on living? Or is the language of the Christians just too full of blood for that? Just as the Spaniards won't give up their bullfights, the Christians can't be persuaded to give up their redemption through blood.

Take the movie that infuriates Christians, the blasphemous "The Last Temptation of Christ", whereas Jesus hangs dying, he has a dream: A woman balks his plan and sabotages his redemptive death. Also, while hanging on the cross, he dreams that his "Father" has allowed him to live. Even the cinematic angel says: "Your Father is the God of compassion, not of punishment, ... the Lord doesn't want your blood." Jesus then climbs down from the cross, walks down Calvary, and marries Mary Magdalen.

That angered Christians to their bones because married Jesus disturbs the Christian image of God, while the though the cruel Father of "The Passion" doesn't. The Son's love has to manifest itself in a bloody sacrifice, but never in the act of love. Jesus has to pay a high price for his father's compassion. And even in "The Last Temptation of Christ" it is all just Jesus' dream because even as a dream it is infuriating. Dreams of God's compassion are just deviant fantasies.

Whatever you say. 
The concept of redemption through blood did not originate with Christians. They were quite late to that game, in fact. 
The history of sacrificial blood goes way back. You should look into it sometime.
