First, while the X post was not intended to be a political statement

Not intended to be a political statement? Even setting aside agreement vs disagreement, how is this (below) not a political statement?

10 years ago Republicans were the party of big business and Dems stood for the little guys, but today the tables have completely turned.

Again, regardless of whether you agree or disagree it’s like a textbook example of a political statement.

Well, like anything, it depends on context. In this context, it’s not crazy to be on high alert for weird politicized signals.

However, I think you made a pretty good point about its meaning in Taiwan given that this fellow is apparently from there, combined with it being his year of birth. So, context decides and in this case at least it seems pretty ordinary.
