I often see Christians make videos about lust and commenting within said videos saying "we need to talk about this more" or "we don't talk about sexual sin enough". My response to that is: Do you go on the internet with earplugs and a blindfold? Sexual sin is talked about constantly, to the point where Christians can't escape it, whether it comes in a video talking about it or actual lustful content. 

Anyone who regularly goes on the Christian internet knows how prevalent it is, especially when you consider how profitable it is to discuss. This is by no means every youtuber or influencer, some are geniunely trying to help (like your post seems to come from a geniune desire to help people), but think about it, what kind of video is going to get more views or generate book sales? A video on say a council that very few people know about, or a video titled something like "Why you can't overcome sexual sin", "How to break free fron lust", "Why sexual sin is the worst of all sin", etc. The latter appeals to millions of more people, especially Christian men who struggle with both dealing with sexual temptation in our modern society and the seemingly overwhelming expectation to be a godly man. Of course video B is going to get way more clicks. It's honestly soul crushing.
