Not precisely a correct depiction of history.
The Jews in Spain were given the choice of converting to Catholicism or leaving Spain.
The commonly held notion that Jews were tortured and forced to renounce their religion and become Catholics is untrue.
I don’t know the number that creates the myth, but certainly, many Jews were burned at the stake and others converted from such threats. Are you saying that didn’t happen?
You are (largely) right that the Spanish Inquisition did not torture non-baptized Jews. But you are blatantly wrong that Spanish Jews weren't forced to convert. Starting in the early 14th Century, periodic mobs (often led by Catholic Priests) would ransack Jewish neighborhoods, often giving Jews the choice of the cross or the sword. Moreover, in 1492, it wasn't simply a choice of converting or "leaving Spain." It was a choice between converting, or being stripped of your property and forced to emigrate penniless.
It appears that some are either totally ignorant of well documented, historical facts, or in denial, or just plan Anti-Semitic revisionists.
But, there is so just much documentation available on the subject, it is absolutely amazing that anyone could even possibly claim it did not happen.
There are actual letters from people who had lost family members, as well as government and church communications from that event in time that are available to see if you can read Spanish.
The incredible brutality of Tomas de Torquemada, a Spanish Dominican monk, who was appointed Grand Inquisitor is well documented, and matter of recorded history. He is how the Inquisition got its bloody reputation. There is an incredible amount of documentation available from a variety of sources. Including the Catholic Church, itself.
Visit Spain, they have some of the original torture devices on display in various exhibits. Read the little placards that tell you about them. They feature them in many languages.

Also, in regard to Columbus, there is very convincing evidence that he, in fact, was a “secret Jew”. You will find some interesting information here:
