No offence, there is much you don't know about Christianity. For one a Christian theocracy exists today as I showed in a previous image, Vatican City. You said then that Vatican city was a better place to live than Saudi Arabia.
The death penalties for blasphemy and homosexuality, as well as honor killings were under the Mosaic Law legal system. Christ's coming, death and resurrection fulfilled that, so while homosexuality and blasphemy remain sins in Christian teachings, the capital punishment no longer applies and hasn't for over 2,000 years even if some Christians have maintained it. Compare that to the Qu'ran, where there is plenty of wriggle room in the Qu'ran to allow the death penalty for homosexuals, and it has been used for that purpose. Not to mention the Bible commands peaceful co-existence between Christians and all people where possible - Christian and non-Christian alike in Romans 12. The Qu'ran's mandate for non-believers who refuse to convert (which most Muslims don't follow thankfully) is death or subjugation.
The Spanish Inquisition would've been unlikely to put you to death, even if you were a heretic. However, since you're not Christian you can't be a heretic; as a non-Catholic Christian I'd be more at risk of a heresy charge than you if they were still around, and I'd still take my chances with them rather than Saudi Arabia's punishment for evangelizing a religion other than Islam (which is death).
As I also showed in a previous post here, the Spanish Inquisition only executed around 1-in-40 of the people they trailed. They also were often fairer than secular courts at the time, allowed some freedom of speech and didn't have total control over Spain, let alone the Spanish Empire.
