Christians stopped fighting the crusades centuries ago, muslims are still fighting them 800 years on.
I could only read the first link you sent, the other has paywall. But at first glance its already referring to something that happened more than a millennia ago. The FP article tried its best to draw on modern day parallels of "violent christian extremism" like with the example of how "Rumors flew in Moscow that there would be a pogrom to celebrate the day Christianity came to Russia, and that the police were handing out addresses of Jews to the public" or how "Dylan roof, by some accounts, came from a church going family". Both are very tenuous links, with no concrete evidence marking a correlation. On the other hand, an islamic state still exists, the vast majority of terrorist attacks come from muslim extremists, and most if not all of the remaining theocracies in the world are islamic, run under the observance of the oppressive Sharia Law. That's what Elvin means when he says it's still being forced. You have the choice to ignore an evangelical trying to convert you in America, or anywhere else. You don't have that choice with islam in other parts of the world. Conversions to any non-muslim faith, or none, can result in death, even in fricking 2022.
