Why was I banned from Facebook for saying "I love you"?

[brassknuckles11]

I was being called a faggot and told that gays all need to die. Instead of dropping to that person's level I simply said "Well I love you, I want to be your best friend." I reported the person to Facebook and I was banned for 24 hours.

Here is a screenshot of the message:

I am livid. This is not the first time Facebook has banned me for no reason. What can I do? I want to get the word out so maybe Facebook will pay better attention to who they place a ban on.
For clarification, the name I was called was F A G G O T
Also, the message says 12 hours but they did indeed block me for 24 hours, I still cannot log in.
For the record, since somebody in the answers seems to think I said something else. I did not. This is the comment Facebook banned me for. The other person was flaming me over and over again and saying a lot of rude and nasty things. I didn't say anything more to him that would have gotten me in trouble.
To whom did you type the words "I love you"? The person who was telling me they hated me and all gay people.

Why did you type that statement? My thought process was to kill em with kindness. I was doing the opposite of dropping to their level.

What led up to you typing that statement? This person calling me a faggot and telling me to die.

I don't understand what is unclear about this...........
