Terrorist attacks in Brussels

a cursory research seems to suggest it was quite comparable to Israel's Hafrada. "Forced conversion", however, is antithetical to itself, and in many cases were found null-and-void in the coming Inquisition.

Israel's Hafrada does not apply to the million or so Arab Israeli citizens living inside the borders of 1948 Israel.
It also does not say "leave, leaving all your belongings behind, or be summarily executed."
All it does is keep people who have publicly vowed to destroy Israel, outside of it.
The Jews in Spain made no such threats against Spain. Nor did the Jews in the other European countries that expelled them before and after Spain did.

It is interesting to note that during this period, the Islamic rulers and people were much more hospitable to Jews than the Christians were. If you read the article you'll see that the Jews in the Iberian peninsula thrived under Islamic rule, before the reconquest by the Christians, and also fled to and were welcomed in the Ottoman empire after the Alhambra decree. So, not all the world was as not-atrocious-for-its-time as you paint the Inquisition to be.

Fact is, Christianity is not inherently peaceful, and Islam is not inherently violent.
Both have had their peaceful periods, both have had bloody violence done in their name.
Which doesn't make it justified in either case. It just makes it so villifying the religion itself, rather than those who are using it as a tool for destruction, is invalid.
