there is no argument against it that stands on logical legs. The arguments either just talk about boogie men like corporations, globalism, and the "establishment" or somehow gets mixed with fear of Mexicans/Muslims/Chinese taking jobs.

I assure you, globalism is much more than just a talking point "boogie man", and there is plenty of very valid discussion to be had on the matter in that aspect, seing as according to the supreme law of the land in the US, the Constitution, treaties and agreements entered carry the full weight of federal law. Not a superficial point at all. Which is also why most of us paying attention realized the passing of fast-track was such a large blow to the control mechanisms for such treaties.

Whatever your viewpoint on the TPP itself, to negate criticism of it as lacking any "logical legs" is intellectually dishonest at best.

This is untrue. It encodes the US's broken anti-circumvention law on the global stage, which restricts our ability to freely trade with eachother. There are gains from trade and the TPP should not be used to stop them.

I didn't hear that argument from either the left (bernie - corporations) or right (rust belt voters who barely understand email). only some small online subset of tech savvy users.
