Shadowcry, an inquisition is a legal trial. In most countries in Europe the Inquisitional system still operates. In English speaking countries the adversarial system operates.
Inquisitions were started by the Church to investigate those Catholics accused of heresy. Non Catholics did not come under the jurisdiction of the Inquisition.
You speak of the Portuguese Inquisition, did the Church authorise this Inquisition or the Portuguese government? If it was the Church when and under what pope?
You said that the Church supported hate and discrimination, can you give me an example of that?
If you are interested read the books I mentioned, they are not vague and they cite primary references not just looney tune ones. If the books are a bit much go to the sites other people have listed and have a read of them. Once again, they should cite references which can be checked.
All the best
