Arrogance is a pretty easy weapon that takes less effort, the really harsh one's are reserved for the really important cases :> .
I'm scary of justifying myself even more, because I already do that way to often. I could try to write a little less though and care a little more about the quality of what I write again, as I know I cut a little too hard on that lately, but seeing the same discussions from year to year contributed towards this behaviour.
Regarding Forrests it's actually really simple.
Hammers in the early game, are the rarest thing available, and they're the most valuable thing available. Getting 30 hammers from a chop is about 3 times as much, as a city at that time produces normally, which is not even important, because chops + normal production stacks. The time until Preserves are available is so long, that even if they'd have to be Goldmines to even come close to what the cities one can conquer with the units built by them can produce. And even if they were Goldmines, it wouldn't matter that much, because at the time those mines would be available, one could also have a fully grown Town on that place, which would be even better. Conquering cities giving resources solves the problems with the Healthiness, that some people argue for. It conquers the problems with Happiness too, and the advantages you get from the new cities multiply over time with even further cities conquered, resulting in an overall better winning date. So the problems Forrests or even Preserves solve, would not even exist if they were chopped in first place. Chopping basically is a totally unbalanced tactic, as it's Hammer-bonus is way too large and as improved tiles are even stronger than forrested ones via the various Civics. The fact that a Worker is built (or stolen

) once, but works for free from that point onwards, makes Forrests free Hammers in CIV, and it's hard to argue about something that's free and that benefits, right? :>
