I stated my reasons for the vote in-depth within the very post you quoted.
But if you're asking about militarism in general I can say more:
To start off, I don't think we've seen "nothing but problems by becoming more militaristic". Before this, I didn't see any clear problem with pursuing militarism and it more had to do with unlocking metal weapons/having high Martial and Negative Stability. Are you going to argue that we shouldn't of unlocked ironworking?
Additionally, I toyed a few times the idea of forging an empire (if only to gauge how open people were to the idea). We have an advantage over our Cooper Age counterparts and I think capitulating on it will be useful in the long run.
So, I was talking militarism in general. My whole thing is that this empire building you want to do, can be done quite well
without conquering our way through our neighbors. We have the tech, infrastructure, and defensive advantage to outlast them entirely. Eventually they fail. We've seen every civ around us detonate internally, and mind you that was
always caused by excessive conflict. What we are seeing now? It's just a little preview of what happens.
The nomads are a great example. They literally are full martial and can barely hold a coherent civ together, and require heroic units to unite them. It's only after they
let go of some of their martial traits that they actually built the empire they've got now. The Spirit Talkers? The Dead Priests? The first literally couldn't stop attackig or they'd destroy their civ, and by continuing to attack, destroyed their civ. The Dead Priests forged an empire for a while but had to let go of many of their raiding traits to actually make the empire worth anything.
We have forged an empire that has so far outlasted all the others with almost no instances of civil unrest. If you recall, the others broke apart Andrew reformed multiple times. We have a higher population, a better tech base, and a better infrastructure base than anyone. We aren't going away. What we have done for the last 80 turns has worked, and worked well. Changing it for a strategy that has been shown
not to work is patently foolish.
So, when you say we should capitalize on our advantage, I'm going to say that we already are, to a massive degree. This temple? The Palace? Our rediculous ability to basically buy whatever we want because we have such high Econ? The tech advancements in chariots, roads, medicine, boatbuilding(soon), metallurgy, even warfare, were all made possible by iron. This is how we are leveraging that advantage. Doing it through conquest is pretty boring, honestly. That advantage isn't going away either. Eventually, sure other civs will have iron working, but when they do, we will have our built and our grown them so far it won't make a difference. Iron isn't the be all end all. We are literally out econning them, and it
works.
As for Iron working, of course I supported Iron working, but supporting iron has no direct relation to militarism. It makes superior tools and is a branch point for hundreds of technologies. I'm a little confused as to why you seem to think supporting iron means going a more militaristic route, especially when I and most of the rest of this thread voted to build
tools first, rather than weapons.
By the way, a couple things in your post:
Shouldn't have*
Pretty sure you meant capitalizing
