" Under attack, sentiments harden into dogma"
That seems correct to me. You name the issue and you can find the talking point....I mean dogma attached to it.
"Under attack, sentiments harden into dogma."
Sentiments might be a little unclear. So let's define it:
Sentiment: a thought, view, or attitude, especially one based mainly on emotion instead of reason:
Notice, it doesn't say "facts"
"When your views, opinions, and thoughts are attacked, you proclaim those views, opinions and thoughts as unquestionably true."
Or maybe something like
"Tarrifs are bad, they are are tax on consumers" no matter the actual evidence
Or a hundred other examples.
