OK, I think you misunderstand: I'm not being nihilist. It's only nihilist if you're driven by literally nothing but logic because there is no logical point to anything. We're not nihilist though, because we have emotions driving us. I'm fine with that.
I'm also not arguing that rationality doesn't exist. That would be perverse.
Secondly, I think it's a stretch to say that I disagree that actions are rational if they further the goal. If the goal is not rational, then the actions are only marginally rational at best. If, for example I was driven to spend the rest of my life wandering round dressed as a giant chicken, well, it would a stretch to call the endavour logical.
The thing is, I believe as the expression goes "you can do as you will, but you cannot will as you will". In other words the goals you have selected have no basis in logic. So I agree that you can act logical to achieve goals, but you're still acting logically to do an ultimate illogical thing.
Anyway, in my mind people are irrationally tied to a place and a particular group of people. They'd rather pretend to be something they're not than go and find a group of people who accept them as they are. Personally, I find that illogical, because if your goal is maximising happiness, then there's a much better local maximum not far grom the current local maximum.
