Yeah, I thought that was kind of weird. As I Am is still up (which coincidentally, that reaction video was released a year ago today), but the others are gone.
I really enjoy their videos. They haven't really strayed too far from their roots, which some of these React channels do once they get popular. I used to watch one called Vinand Sori, but they kind of got annoying. Their "thing" is that it's "Christians React to.." and they would give really in depth analysis of the song, but they kind of got annoying because they never did any research into the band or song and would immediately try to connect it to religion even if there wasn't any way to connect it. They did Ghost a lot, which was their most popular videos for awhile and with Ghost, you can't take the lyrics at face value--they aren't all about Satan and stuff. They did Ghost's song Rats once and they were listening to it and afterwards said: "It's about the Christianity, when they say "Into your sanctum, you let them in" they're talking about God and how it's wrong for people to do that." or something to that effect. But if you read into what the song is about, it's a cautionary tale about our world and the new "plague", social media and politics, etc. It's not an anti-religion song and because of their interpretation of it, they wrote the song off. That and every Ghost song, they would say "Sounds like the last one, they have no variation. He writes the same song over and over again" It got kind of old and the comment section reflected that. Oddly enough though, they really like Cradle of Filth
