The fact that people felt and acted differently in previous times regarding yarmulkes is history; the issue itself though, is a hashkofa and halacha issue – of what relevance is there to note how someone or another feels about it?
People used to not be careful about lashon hora – as in it was an unheard-of meis mitzvah. Of what value were the people’s feelings as to the definition and application of our understanding of the issue? Granted it’s not a clear violation, but it is subject to halachik and hashkafic discussions in the poskim. They didn’t take into consideration what average baalebatim felt, so why should we?
