Christianity too, bud.
Perhaps, but there is a difference.
As screwed up as it is, denominationalism happened in Christianity, in many cases, because people recognize a wrong direction in the parent body, and are attempting to correct it.
I have openly condemned the Inquisition and a great many other things that people did "in the name of God" or "in the name of Jesus".
I'm not making a joke or excuse for it, but even in the Bible it's clearly seen that the "devil" goes to church too. Man made organizations are best corrupted from within.
People have different experiences. One person's freedom interferes with another's freedom, even when no "evil" is done, as I showed above.
Even if you prove an objective standard of morality to someone, you cannot force them to obey it, and certainly the Old Testament approach or the Inquisition approach is just as screwed up in some cases as the "evils" it was trying to prevent. Really, the Inquisition was just plain evil to begin with, and the result of a totally corrupted and misguided understanding of the Bible, combined with a backdrop of confusion and superstitions about Jews and other groups.
Had the hypocrites read their own Bible a time or two, they would have found this:
16For if the firstfruit be holy, the lump is also holy: and if the root be holy, so are the branches.
17And if some of the branches be broken off, and thou, being a wild olive tree, wert grafted in among them, and with them partakest of the root and fatness of the olive tree;
18Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee.
19Thou wilt say then, The branches were broken off, that I might be grafted in.
20Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear:
21For if God spared not the natural branches, take heed lest he also spare not thee.
22Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness, if thou continue in his goodness: otherwise thou also shalt be cut off.
23 And they also, if they abide not still in unbelief, shall be grafted in: for God is able to graft them in again.
24For if thou wert cut out of the olive tree which is wild by nature, and wert grafted contrary to nature into a good olive tree: how much more shall these, which be the natural branches, be grafted into their own olive tree?
25For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
26And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob:
27For this is my covenant unto them, when I shall take away their sins.
28As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the father's sakes.
29For the gifts and calling of God are without repentance.
30For as ye in times past have not believed God, yet have now obtained mercy through their unbelief:
31Even so have these also now not believed, that through your mercy they also may obtain mercy.
32For God hath concluded them all in unbelief, that he might have mercy upon all.
That can be a hard thing to understand, but the gist is that Paul is saying to the Christians that Jews who do not believe should be respected, and that God is able to save them too anyway, eventually.
Therefore, the Inquisition was not only evil, but it was anti-christian at it's very core, and directly opposite of what the Apostles and Jesus taught regarding behavior towards unbelievers.
