My questions are more directed at the nihilism aspect of your OP.
Are you nostalgic about anything to do with your respective culture, customs, traditions, history, heritage, identity, or your ancestors story? Or is it all meaningless and insignificant to you?
Nostalgic? I am not sure what you mean here. I can talk about
customs and traditions. Customs and traditions of many cultures are interesting, but not particularly productive or relevant in today's world. It's actually holding back progress. Many traditions are full of superstition and illogical nonsense. The problems arise when forcing a tradition overtakes logical decisions because of a parent's forceful hand, peer-pressure, etc. History is full of examples of forcing people to do dumb shit because of "tradition".
Its meaningless to me but not to other people. So there is only so much I can ignore. We are all a victim in some sense of people's or cultures collective stupid beliefs. But mostly I ignore their dumb shit when I can.
Identity is a tough one. It is something personal people choose to hold dear. And it varies. Muslims and Jews use religion as an identity, regardless of heritage background. People with gender disorders identify the "desired" gender or even made up genders as their identity. I used to argue till my face turned blue about that, but it's pointless, people latch on to "identities" to fill a void. As long as they are happy who cares, as long as they don't force their shit on other people.
Do you believe in preservation? Cultural preservation, wildlife/ecosystem preservation etc.
I believe in science, evidence and compassion.
A culture devoid of these things are not worth preserving. Of Course I believe in wildlife preservation, I have kids, they will inherit a more dirty world than I was born in. We are destroying our planet and destroying ourselves. We are the dumbest animals on the planet.
Do you enjoy a good MMA match, or do you not recognize that one MMA match has value over another? What about the opposite sex? Do some potential love interests engender stronger feelings of passion, emotion, value, and perhaps even purpose, or do you see that as some sort of "construct" or chemical trick?
At this point I doubt these are serious questions. We are a result of evolutionary process and chemical reactions. It's a nature vs nurture debate. You can't deny it's mostly a chemical drive.
