I don't think both parties are the same, but I do think both parties are having public, ongoing debates about globalization. Their answers vary over time and candidate. It's not being controlled by shadowy elites, nor is it being shamed as "politically incorrect" speech. Using your definition -- no one thinks this discussion is "offensive."

It's hard to see the major legislation being passed or presidential campaigns being run and say otherwise -- I think the onus is on you or the OP to submit evidence wherein the elites or whatever shut down the conversation or react with indignation. I've provided my evidence in this thread already.

As for globalization versus not. Again, what is the alternative? Be concrete. To me, globalization is capitalism or free marketism. Put another way, it's a market based economy.

Once upon a time, people believed that planned economies were an alternative to globalism, but I'd say the jury is in and no one really believes that anymore. So, seriously, what is the alternative?

I imagine most people agree that child / slave labor are abhorrent and that we should add safety rails to globalization to address those issues. But that's still globalization.
