Parents (Mainly My Mom).... They Confuse Me

So a while ago (I don't remember how long ago) my brother told my mom about how this kid in his school was wearing a shirt that had something to do with Grand Theft Auto V and she said something that I thought was kind of weird, and that was something along the lines of that because his mom lets him play games like that, he's a naughty kid. Now I have no idea whether or not that is true since I don't know the kid myself, but part of the problem is that playing games like that would make a kid misbehave, which I do not believe to be true unless there is something wrong with them mentally to begin with and that is another story but I kind of had to go "Really?" because this was the same person who got me San Andreas when I was my brother's age. I should also mention that it'll always be dependent on how well the kid can process things like that and some can handle it at earlier ages than others. She has also been hypocritical at times or thinking that one thing was bad while another thing that was objectively worse was fine; example being comparing the sangs Get Lucky to Blurred Lines, which I could get into why I think that argument in incredibly flawed, I'll let it slide this time. The sad thing is that most people acquire their taste in films and music from their parents, either directly or indirectly and I like to think that I got most of my film tastes from my mom while my musical tastes comes from my dad (a little from the others on both) and when it comes to having a difference of opinion when it comes to those things, I like to consider it that they did a good job parenting me, having exposed me to things that they thought were good as long as they were sure I could handle it (which I could for the most part) and I have them to thank for my taste in things, even if it leads me to dislike a lot of theirs in the process. It would be easy to say that, "Oh this has too much swearing or too much violence" and etc., without actually considering the context of things, which is another thing I learned from them. The context of why things happen is important to explain to kids about movies and video games, why one is more inappropriate than the other. This was also part of something the other day when I was watching an episode of Trigun when everybody had to come to the living room to eat and it was episode seven (it was difficult to listen with people being loud and no subtitles) and there was a scene where the kid in the episode who was with the people hijacking the sand crawler had a gun held to his mouth and my mom thought it was a bit much even though nothing happened to him. Now I think she didn't get the context which I could understand if she wasn't paying attention but I wish she would have just let it continue on since it's not like the kids haven't seen that kind of stuff before. But what is the point I'm making here? I'm just here to say that I do love my parents even though it may not seem like it most of the time since they made me the person I am today. I just find it weird that my mom who exposed me to a lot of things as a kid that most would have frowned upon (and I turned out okay for the most part) has turned into kind of a prude similar to that DVD-R Hell episode Brad Jones did on Deception of a Generation. Maybe it is my duty to be the purveyor of that kind of stuff now that my mom no longer wants to do that, to make sure that my brother turns out okay before it is too late.
