I agree with Blu. Wholemeal pasta is made up, just as soy milk is made up. Where are the udders on a soy bean?
If you don't eat dairy because you are genuinely intolerant or allergic, I can understand why you would want to replace it in your favourite dishes. But if you don't eat dairy because you think it's not natural to eat the milk of another species, why on earth would you substitute it with something else equally unnatural that was only invented to replace the foodstuff that has been used for centuries? Soy milk is not a mainstay Asian food (used mainly for feeding sick old people) either, and babies and children are certainly not fed on it.
But seriously, if you eat wholemeal bread, cereal, brown rice, pulses, lots of fruit and veg, you really don't "need" wholemeal pasta. I mostly eat wholemeal bread, but I don't find all white bread disgusting - lots of it is delicious. So I can eat wholemeal pasta with the right sauce, but it doesn't stop me enjoying lots of other traditional foods - egg noodles, rice noodles, white pasta, buckwheat pasta. I draw the line at spelt pasta though.
Though I have a bee in my bonnet about over-processed food (not white pasta, which has been around for centuries), I also have a bee in my bonnet about certain types of assumption about foods - eg dairy bad/soy good, white bad/whole grain good, high fat bad/low fat good, four legs bad/two legs good etc.
Oh. That seems to have turned into a rant. Will go now.
