He was hired in a different time.
But I don't find his humor innocent.
1. They weren't funny.
To me his posts scream a super homophobic guy who we later find out is gay. The fascination he had with child rape jokes, really makes you think he either has done that/does it, or has a secret desire to do so.
Look at the post above you. I googled the guys name and rick and morty and there was only ONE article about it. That was from Breitbart. Where is the rest of the press? Hell even this James Gunn story got like relatively low media coverage, and nearly half of it in defense of him. The holllywood/media always seems to shelter or look the other way when it's related to pedophilia. I feel it's like the whole Winestein situation. Where "everyone" knew. I found that funny when it came out. I had no idea on who he was, but was not surprised in one bit hearing all I heard. Felt like that was what we all knew was going on in Hollywood. Yet who is all surprised and outraged? The media and Hollywood actors, the very people that you know damn well knew of it first hand.
Making inappropriate jokes is not the same thing as the Harvey Weinstein situation where someone used their position to try to force women to sexually compromise themselves. People can have a foul mouth and still be a good person and be able to contribute to society.
