Hi /u/oli123x1,
I can only offer impressions, so here it is: an answer. You are already 'honing in' on something important, I think, when you say there is, in some specific works, "...a certain grade of disrespect to Christianity..." To begin, it isn't really the case that video games or movies arrive in advance with an adequate gradation system as it concerns acceptance or acknowledgment of what might be understood by true Christianity - even if by all worldly, secular standards they are pre-rated readily by committees: G, PG, PG-13, R, and ultimately X.
So it is not simply that Christians somehow ought to avoid X-rated movies or video games. For that says nothing yet of which respect here is pertinent, in all practicality, for Christians. I want to pause here for a moment to appreciate your awareness of this practical respect for Christianity, before answering any further. Now, that said, I should also add that I am not myself, although I am an X-ian of sorts, a good practical example of this, considering as I'll actually set out to view such aesthetical "works of art", i.e. watching films or playing video games, which may outright attack Christianity in this way. As judged by ethics committees, they might even put out an X rating to such actions or behavior.
And yet, in being so classified as "works of art", I typically think nothing of it, since in art there is generally a certain "respectivity" or even something of the sublime. This type of tracking respectivity, i.e. seeing this with respect to that, even if some Christians find it on the whole to be "yucky", usually allows for the Christian to abolish it in the face of ever more obscurity and obscenity. As they say, one can anchor again & always to God. This isn't a license for sin, so much as it is an awareness of available perspectives and how that of Christianity, if well worked out in particularly addressing them, obliterates it.
Christianity, in many if not most practical respects, withstands outright attacks. Christianity is that in which perceptions of an assortment of changing attacks are "radically altered", in a way. Think of all the tyrannical oligarchs that Christianity overpowered! The Psalmist David often wrote about being surrounded on all sides by enemies. And yet, his perception of another attack or encounter with the next arch-nemesis did not obliterate the courage that is perhaps a shining characteristic of Christianity as such. What is more dangerous to the Christian than that which is perceived as an attack, rather than something classified as a "work of art", is something significant which is way serious in its sense of humor. If something is said in a humorous context, then people laugh, even if that thing is deemed offensive. This happens also in watching films and in playing video games.
What happens to Christianity if the significance of this laughter at it is missed? It gets replaced by Beyonce worship, for instance. The sea of whatever is in the water envelops it, finally surrounding the resistant substance that Christianity is or is supposed to be. I don't think that you are a bad person, nor do I find that you are necessarily "doing a sin" in any of this, although one should in all actual activity realize that indeed it is founded in sin. It is in this other sense of humor which whatever principles Christianity upholds are forgotten such as it is.
