You can't. Facebook does not support unliking a post on Facebook by someone who is no longer a friend
No
you don't
Log out of Facebook, turn off your computer, and go visit this individual in person and ask him/her to be your friend. It's quite simple and the true way to find "real friends" unlike the social nutwork.
if you like the comment then you dont want to any more there is a thumbs up like when it says like it will pop up unlike that is how you unlike things.hope it works out for you guys
Unlike the Answers facebook page
Scroll to the bottom of the photo and tap the "Liked" button once to unlike it.
Go to the page you dont want to like anymore, Scroll down and on the left hand side there is an "unlike" hyperlink, Press it and you will no longer like that page.
You visit that Page and at the side there will be a button saying unlike click that.
Unlike the Answers facebook page
because "unlike" in facebook context means to undo your "like", and if you "unlike" something you don't say I hate or dislike it, you just want to say I liked it and now I found that it doesn't appear to be appealing to me.
If you have to delete someone on face book go down where it says report abuse and there click delete person. Your done!
yes you could, but one after another facebook takes a long time to delete if you are deleting it.'
