I am not ignoring your post, I am ignoring your open ended questions, such as should love be a right?
Define love. Can you see love, feel love, taste love,,,,?
This is where we may have an issue, you see, from my perspective I don't tend to have blind faith in anything, I am a proponent of skeptical logic, but in this one rare area I believe in love. I have faith in it. I believe I have seen and felt and... well not tasted... but seen and felt love.
Love from my perspective (if it has to be defined) can be broken down into three concepts. The ancient greeks have three words for love that work perfectly.
(here are my amateur explanations and definitions of those three concepts, sorry if I'm not as well educated as some in the area and I'm happy to have misunderstood if someone else would like to correct me)
1) Agape - A type of unconditional love you can feel for a spouse or family member or particular activity that you have an unconditional enjoyment of
2) Eros - the erotic love two people can experience together or feel for each other (although you can also according to the ancient greeks feel this love for things like art but I'm not going there right now)
3) Phileo - The kind of love you would feel for a brother or best friend, a kinship between two people.
When you feel these three things for another person and they feel the same for you, that's what I call love.
I can see and hold my AR15. I can see the ballot box, and I know what person I am voting for. Love is what? A feeling. How do you protect a feeling?
I appreciate that you can't feel and hold it in the way that you can an AR15... but concepts and psychological states do clearly exist in the world, so they need some consideration.
If we were to use your argument that you can't protect a feeling in legislation then you would have to throw away all notion of ownership, afterall owning a piece of land is a feeling that has been put into legislation, you'd have to throw away the rights of the mentally ill, after all mental health is a subjective experience that includes a set of difficult to define feelings that the person experiences. Pain is just a feeling, but we legislate against things that cause pain like torture.
How do you protect a feeling? It's very difficult to do, but we do it every day in every aspect of our lives. So why shouldn't human beings make it a rule that everyone has the right to love and the right to experience physical love with another person capable of understanding and consenting to engage in that love?
Wow, this thread has grown almost as long as a rudeguy 'special'!
Really did!
Edit: Turns out there is a fourth in ancient greek "Storge" a rarely used word in ancient greek that means affection... Interesting.
