Unlike you, a good majority of men on this planet like to have sex with women. Are you going to honestly tell me that during an apocalypse people aren't going to be fucking any chance they get? Look at dumb ass Laurie on the Walking Dead. Hell, you know Joel was tagging the shit out of Tess. And it's not like there would be an abundance of contarception available. These people barely have fucking food. The question is a good one. Not seeing any child infected is pretty fucking dumb now that I think about it. I guess it's just Naughty Dog's way of avoiding an already sensitive situation considering the game is as graphic as it is. Could you imagine the outcry if Joel had to curb stomb a ten year old, infected or otherwise?
