OP mentioned masks and homeless. This sub-thread has 5 comments about homelessness in San Francisco, and 69 comments about masks, and it's far more interesting trying to understand the homelessness situation in SF, which is absolutely bonkers IMO, than the same old hot air talk.
First we had the COVID experts and/or denialists, now we have the mask sceptics. I really can do without that.
In Britain, a lot of my friends got upset about Brexit and Election Results and said things like 'we told them not to vote for..., then we told them again to vote for...' - people do not like being told what to do. You gotta win hearts and minds. Sure, a lot of the more vocal ones are a lost cause best left to their own demise - but it's still worth it for most.
Like it or not there will always be shades of grey and discussion and nuance. Trying to ignore that is how you get extremism and identity politics. If you're tired of talking about something - don't talk about it. But oversimplifying and becoming absolutist is dangerous.
