"religious people" are not the problem. Entitled, judgemental, hypocritical, and bigoted people are the problem. Many of those people would be the same with or without religion, but granted they are doing it under the guise of religion. People are always going to have beliefs about our existence, so it seems foolish to be done with anyone that has some form of belief and discusses it.
Religion should not be forced on anyone ever, which is why separation of church and state is so important (and being actively being destoryed). But adding a small expression of your beliefs to ythe end of your video is hardly pushing it on anyone. The worst impact it's had is all the comments being more about the prayer than the content of the video.
All that to say, you're absolutely allowed to refuse to consume anything made by someone with faith in something. You definitely aren't missing much from Network Chuck's videos. But I do think it's a slippery slope to generalize, given the amount of objectively good religious people throughout history. I wouldn't group them with the objectively terrible religious ones
