When they say "God is love" I don't think they are speaking literally, because love only exist in the context of human thought. If you are going to claim God only exists in the context of human thought, then you are saying he is no more real than Santa Clause, or Buggs Bunny. I think most theists will take issue with such a claim.

First of all, 'they' did not tell me anything. Jesus was asked point blank, " who is God" and his answer was "God is Love." It's quite literal.
I do not claim that love only exists in our 'minds'. I believe that Love exists in all things and is a measurable energy.
Let me now address the atheist, that refuses to believe in Love even though he believes in love. Lol....
Lets start by confirming that you do believe in love (lower case).
How can this be? You admit you believe in a yet unmeasurable, intangible idea that 'only exists in the human perception.' It does not appear on any periodic chart. It is not yet clinically tested and would not pass the test for scientific proof. Yet, you still believe.
You believe because you can feel it. It's real to you because you have experienced it first hand. You undoubtably have benefited from it, as have we all.
Now, I assume that you are unwilling to accept that there could be a God because it would mean that you are liable for your faults and mistakes. I think your stubbornness comes from the fear of condemnation. Is this a reasonable assumption, on some level?
So, what if I told you that there is no fear in the acceptance of Love. Love is all the things that you believe it is. Love does not get angry or condem. Love does not adhere to any formal religion or belief system. Love simply is love. There is no burden to carry, no mission statement, no terms of acceptance. You do not have to apply to be accepted.
In fact, even you, a self proclaimed atheist, have accepted love and all it's benefits into your heart. I know that once you experience love, you will never be happy without it. True?
I believe then, that you have Love in your heart. In my view, all you have to do now is be loving to others, and you have fulfilled your requirements for salvation. If you choose love on a daily basis you are a godly man whether you admit it or not. It doesn't matter whether you deny it or not, it simply is what it is.
