Of course admiring your guro interest in you public Facebook account where everyone can see it is stupid idea. even if you wont get judged there may be awkward situations when someone will ask you to explain it and it may be pretty hard to tell why you like little girl being fucked in the eye socket.
even if they wont get terribly disgusted, you will get reputation of extreme pervert.

So you should not openly admit such thing if you want to make friends you should just give some hints and if someone mentions those hints he is admitting his own involvement.

I think main danger is not that you will get fired or that your family will hate you(as it will not happen), but because you will never know what other people think about you and what effect this has on their decisions.
