Exactly. By content, here is a book on Amazon[1] where the author openly tells stories of rape and incest and somehow it's all Ok. Pretty much the same as Game of Thrones and those Steam games.
You are not in agreement. The person you are replying to is being sarcastic. They feel that a HBO produced tv show with incest is art that needs to be protected while an indie dev game with incest is trash that needs to be censored.
The fact of the matter is you will find more people willing to publicly bat for GOT than you will find people willing to bat for an "indie incest non-con game". And it's not like GOT has not received criticism for its content or that people haven't tried.
The movements here (the pro-censorship movement & the anti-sexuality movement) are mainly driven by religious beliefs, and as such, it comes as no surprise that they do not want to apply censorship in a fair or even logically consistent way; they merely want to ban things they personally do not like.
As I pointed out earlier, it's also valid that they are savvy enough to pick their battles and divide and conquer - you can't take down a critical mainstream success like GOT or GTA, but you can go after fringe games with content most people would be uncomfortable publicly defending.
