T'Pol seems to me so logical in her choices, so Vulcan. (Well, maybe if she were been a little less ambiguous with Trip!

I mean: doesn't a Vulcan, because he/she is a Vulcan, chose and pursue his/her path?
Being Vulcan doesn't mean, for me, being equalized.
And, once again - and I ask for your pardon, if I underline this once more - in what are Vulcans different from Humans? If I'm not mistaken, in their rigour, in the way they handle their emotions (emotions, that's a fact, that they have).
Frankly, if I go with my thought to the whole ST, I see only a more or less great amount of more o less intelligent or stupid attitudes (feelers, ridges, skin colour and some other stuff apart) which try to make as aliens the Aliens.
And some diversities of behaviour which are not different from the diversities we can see between the different people who live on Earth.
That's obvious, on the other hand, because all these Aliens were thought by Humans, and - logically

So, the way all the writers (all of them, not only the authors of ST) use to describe Aliens is what I wrote above: feelers, ridges, skin colour, strange behaviours etc, etc.
But all these things are the reflex of what we are.
That's the reason because of which I'm very cautious about "Vulcan way" or Human way" or "Andorian way"...
In reality, we are simply talking about different behaviours which are the same behaviours of us, a little modified, and - not infrequently - distorted, sometimes to such an extent that they resound factitious and contrived.
