You're contradicting yourself here. I was going with your own definition of love, "Love is a feeling of appreciation."
Response: Yet I stated it was a feeling of appreciaton that derives from being the caregiver and protector of someone or being proteted and cared for by someone. Whereas your example explicitly stated that love involves not protecting someone, therefore allowing harm to come to them. So your example fails, for your definition includes the very opposite of love.
Yet more question begging that contradicts your previous question begging.
Response: Yet your inability to refute the definition and the fact that it's stated in the dictionary proves otherwise.
It is a preposterous assertion that "one gender claims to be only able to sexually attract to the same sex and not the opposite sex." Genders do no make claims. Individuals do.
Response: Your rebuttal makes no sense. A gender is made up of individuals, so stating that a gender made a choice includes the fact that an individual made a choice. It refers to the individuals within the gender. That's the equivalent to saying that if a person says that China chose to host the Olympics, that's wrong because China does not make choices, individuals do. So your equivocating is sad, while your ducking and dodging to answer the quesion as to what is the difference between the sexual nature of attraction between men and women that makes the same sex love each other sexually, but not to the opposite sex, supports your denial to the fact that homosexuality is based on lust, not love.
