What do you thihnk about love?

I am writing an oratory about love. My topic is going to be something along the lines of “Love has become a taboo subject in our society.” I would like to know of and important philosophers/philosophies that support/reject that idea. Anything will help. I have been searcing endlessley for several days,a nd have come up with dead end links and non-reliable sources. I have a few sub-points to review, any help on these would be greatly apprieciated also.

  1. People do not believe in love.
  2. People are afraid of love.
  3. People are afraid they will not be loved in return.
  4. People simply do not want love.
  5. People do not love themselves.

Like I said, I am also asking for conflicting philosophy. I need to know what people think about this topic so I can include evidence to waive or at least sidetrack beliefs that go against this topic. Thank you kindly.
