I don't think so.
Love is about everything else, including material things or life.
You are to pessimistic person.
Love, culture, art and science move people and improve their lives, not war or destruction.
Of course, many times we can't avoid war or conflict but, in time of peace, we have chance to grow again.
Love is just chemistry, nothing else. He's not being pessimistic, he's being realistic and he's right somewhat. Weapons and drugs are the biggest busnesses in the world, where the governments themselves are into it very much. Yes, but how was WW1 and WW2 (example) won? by telling the nazis to stop? making art? No, people had to sacrafice their lives to win the goddamn war, sometimes war can't be avoided, war must be started to make things better. Don't be a dirty hippie.
