To elaborate some more, maybe a different framing makes the issue more accessible to the 'conservatives': Imagine someone going into a church and telling the people praying there: "None of this makes any sense, you know. Have you considered atheism?"
I'm a "fiscal 'conservative' small government mind your own business" type who is not involved in organized religion. Much of my family is religious as are many of my friends (from across the political spectrum).
You would be mightily offended. You would decry the indifference to your "way of life" by the evil city dwelling godless elites. Many on your side would try and use any media outfit at your disposal as well as the courts and parliaments to stop it from happening again.
No, some might take offense or disagree with the person making such statements, but I can't think of anyone among my religious family and friends who doesn't understand and value freedom of speech and religion*. They would not try to use the power of government to silence or control the atheist, but they might engage in debate or ask them to leave if they're disrupting a service or event at the church.
*My mother's family roots are Lutherans who fled the Baden Wurttemberg region of Germany in the early 1750s and immigrated to South Carolina. This history is not forgotten.
The problems are indifference / lack of empathy on the one side and the negative narcissism of indignation on the other side. Both seem to be rampant these days, on all sides of the political spectrum.
The problems I see are narcissism, intolerance, and over-sensitivity to any offense on the left. You have no right to be unoffended. Except for libel, slander, and incitement to violence, speech in a free society is not limited by the feelings of others. What you see as indifference and lack of empathy are simply people minding their own business and ignoring things that aren't of any real consequence.
Again, I miss the relaxed irony of the 90s. It's a much better way of coping.
I miss the 70s and 80s before safety culture, helicopter parenting, social media, and the 24/7 news cycle. When shows like All in the Family, Sanford and Son, and The Jeffersons addressed race relations thoughtfully and comedians like Flip Wilson, Eddie Murphy, and Richard Pryor entertained audiences of all races and helped heal the wounds of the past with humor.
