Does my 30 year old boyfriend need to be friends with girls under the age of 18 on facebook?

It's been a ongoing problem, for me. I cannot stand to see him scrolling through facebook on a daily basis and have half of his posts be from teenage girls. Mind you... swimsuit pics, pics with their friends, self photos, all dolled up in makeup (trying to get boyfriends their age I would presume). It makes me sick to know this is the majority of information he takes in especially knowing he enjoys teen porn.

He works in a facility attended by children. The age range of kids he works with is under the age of 12, and male. But, occasionally these teenage girls who also attend will add him, and he accepts.

I asked him to delete a certain person today and he said "fuck off, leave and don't talk to me" then sent a text to my phone and said don't talk to me for the rest of the day. After I spent 2 hours cleaning and making lunch for him in time to get home from work.

Am I way out of line? Because the way he makes me feel like a piece of shit for asking him to clean up his friends list has gotten too old. Also something to take into consideration, I deleted my facebook over 2 years ago.

I am sick and tired of this. FUck.

I know this is not a relationship forum, but I hope we can all agree here that facebook is nothing but trouble and unnecessary drama.
