You aren't recounting the "modern" version of history. You are recounting the English version. It's been passed down since the 16th century. It focuses on all the crimes and mistakes of the Cursades, and
re-interprets the whole enterprise through that lens of the worst actors for sectarian purposes.
The shame that many Catholics feel about the Crusades is not because they know more about it, but because we have further assimilated, and all of western civilization is obsessed with apologizing for the sins of its forefathers. I think its unseemly. History is what it is. Who knows what we would have done in their shoes?
We should concentrate on our own failings rather than judge our anscestors for the hard decisions they made in difficult moments.
Modern Catholicism is also, btw, extremely critical of the US, including many of its actions in WWII. Much of what it did was, in Catholic understanding,
unjustified murder of thousands, and thousands, and thousands of civilians (fire bombing Dresden, nuking Hiroshima and Nagasaki). But that doesn't mean we should simply conclude that the Amercans were morally equivalent to the Nazis or Imperial Japanese, or that they had some alterior motivation besides stopping the spread of facism. Catholics also think abortion is murder, yet that doesn't mean we act as if every liberal who supports it is the active and knowing equivalent of a murderer.
There were some bad men, and some bad events in the Crusades, no doubt. But
they were originally and generally motivated by a desire to liberate Jerusalem from a very brutal oppressor.
As far as the inquisition, it is simply not at all what people think it was, as even the BBC--hardly a Catholic apologist by any stretch of the imagination--has demonstrated:

As for Islam, it has always been a religion of conquest and bloodshed. If Mohhamed was an idela Muslim, and Jesus was an ideal Christian, you should expect "extremists" in both religions to look very different.
But not every sectarian Muslim (i.e., a Palestinian soldier) or every sectarian Christian (i.e., N. Irish NRA soldier), is a religious extremist. St. Francis is an "extremist" Christian.
