What an arrogant assumption you have made that a human being cannot read comic books and literature at the same time

His statement does not imply that at all, so you may want to check it out before you give in the collective outrage.

I read 19th century German novels and novellas in two languages during the week

Lol. What does that have to do with anything?

The average age of comic book fans has increased, so the part of his statement - "But then twenty years or so ago, something happened – adults decided they didn’t have to give up kid stuff," - is true.

The fact that a lot of people on this sub are taking this as some sort of a personal attack is surprising. Bill Maher's words may have been harsh and edgy, but he's not wrong.
