I knew someone that used the vidangel service, but I don't really get it. If you remove the cursing/sex/violence from much of the works that use them, does it not remove context that is necessary? You mention ASoIaF, which is littered with all three right? How can you consume a "patched" version and still retain the themes and messages of these works?
If you don't want to be exposed to these things, why not just only consume content that does not have them in the first place?
