I get where you are coming from and I agree that a lot of people suffer from BO that can be easily remedied by better hygiene. Some have never learned the proper way to shower and some are depressed. Then there are those with medical issues. I think part of what makes the topic of hygiene so awkward to broach is that unless you know they are not showering, calling them out can be less than helpful.
That said, don't fret about the downvotes. They really don't mean much. And my comment was not meant to be harsh. I use italics for emphasis, but not to be rude. I hope this exchange does not discourage you to make comments!
These days, it feels like one needs a disclaimer for every opinion or fact just to avoid setting someone off. I feel like it discourages open conversation...
