We didn't have anyone blaring over a speaker here, but we, like anywhere else, have an assortment of raving maniacs who will yell all kinds of conspiracy theories (They don't really deserve to be categorized as "theories" because of their being either totally impossible to be real, or very very very unlikely to be anything other than a delusion) at the top of their lungs.
In my personal life, I've known a woman my entire life, our families have been friends since we moved across the street from them before I was born. She's a year older than I am, and recently, she sent me a link to a political video about the upcoming election. I made the comment, "Well, if there was ever any doubt he's insane, that took care of that!" You can guess who I was talking about. Uh oh, somehow she went from pretty much apolitical to foaming at the mouth insane. She sent back, "What's insane about it?, and I replied sarcastically, and off she went. 29 email messages later that increased in anger that I wasn't responding (I was in bed), that included more and more links to some really wild websites with all the Qanon stuff and some things I've never even heard of. When I got up, it was late, but I sent her husband an email and apparently this stuff started just before Covid hit and he's totally bewildered as what to do. I just quit replying to her as all it seems to do is anger her and cause tension in her home that her poor husband doesn't need at this point.
