You’re not wrong! I worded that poorly. It should have read:

especially mostly (all?) church-goers

I’ve never experienced any negative opinions of Canada until the current administration. Instead, everyone I have encountered saw Canadians as remarkably similar to Americans (but much nicer) and held them in high regard.

I’ve been stunned by the change in some members of the population, especially church-goers.

I’m confused by this. Can you explain?
