I appreciate perspective. My decision has been made and I've acted upon it. While I work, I listen to and at times watch MMA YouTube videos and the swearing is just off the charts. The "Jesus Christ" and "Gxx Dxxn" quotes crush my heart. I really don't want to be involved with anyone, in a close way if my Savior is being so completely disregarded in that way. Jesus is the focus of my life, and while I realize that others don't realize what they saying, and probably don't even know that it's wrong, it breaks my heart.
So on the basis above, I not only have disassociated my YT subscriptions to not only the MMA videos, but even to others where awful language is used. Amazingly, I subscribed to a drummer's channel (I'm also a drummer) where he gives "reaction videos." One of those videos was over the drummer in a song called "I gotta work sxxt out" or something close to it. So while this Christian posts these videos, I just can't understand why he would promote a band with such ridiculous language. Bye-bye Josh Crawford!
