My point still stands that beginning a conversation about science, technology, or policy with your finger squarely aimed at people you don't like will only serve to start an argument with the people you don't like.
So what’s your answer?
My answer is only an appreciation for "realism" or "realpolitik" in these matters, that people should not delude themselves at the point when enemies distinguish themselves to you by pattern of action and behavior over time. But you should always work for cooperation where possible of course. "Make friends" (where you can).
I'm mostly responding the point that seems to imply political differences can always be overcome, that everyone is always willingly persuadable, and that science and tech or any institutions for that matter can exist in a vacuum outside of politics. People just don't notice or think about political conflict when they are operating amongst political allies or issues don't rise to level of existential disagreement.
And I’m asking you personally.
Doing it over peacetime class and partisan differences is deeply immoral and really stupid.
