I don't think it has anything to do with one poster, but the fact that Trump is really outside the mold of your typical conservative (yes, conservative, not Republican).
Ultimately, in my personal opinion, that's what's interesting about that discussion, not whether 'fans' feel validated by his win (much like progressives of all stripes felt validated by Barry's win, even though he was in many ways nothing like a progressive).
When it comes to economic discussion, there's always been a lot of wedges that you could clearly also break down by party colors: capitalism vs socialism, globalism vs protectionism, free-market vs subsidies, etc.
You might not like Trump's election, and that's fair, but he does shake up some of those lines (at least in theory, we'll see in practice), and I don't think that's particularly bad. Much like I thought the ACA was , but because it happened, it rattled what the ty status quo was, so in that sense, it was utilitarian.
