I believe you have nothing to worry. Remember, it's facebook. It's on the internet so most things really aren't real. For all we know, someone else posted that "I like ******** little girls" and pretended that they were the ones who said it. Don't you think the media would've been on top of them and so would the law.
As for their facts about their favorite cigerettes and alcohol, does that even matter? It's not like they're saying that "we slip opium(sp?) in our cigerettes and smoke it" or something like that. Rockstars are smokers. Rockstars are drinkers. Rockstars (whether single or taken or wanting a one night stand no matter what their relationship status is) like to ********. They're rockstars, it's one of their jobs. xD
I know, and I'm sure hardcore A7X fans agree, that our idols are smart enough to know that if they do ******** a little girl, they would let their fans down. Doing that would ruin their reputation amoung the fans they have and the new fans they are gaining.
So please do not fret over this. A7X would never do something like screw a young girl. And the cigerettes and alcohol? Normal rockstar stuff. I hope I cleared it up for you.
