That's not what my life is like here at all, with all due respect it sounds like you need to step back and take a deep breath for your own sanity.

I would hardly classify traffic announcements on the highway as being that intrusive, just don't read them if it bothers you that much.

Most of what you say regarding social issues, politics, etc. just sounds like modern social media/internet culture, not specifically Massachusetts culture. I find that overwhelming too sometimes, and it's probably best to spend less time online if you feel like you are overwhelmed by that stuff as honestly I don't have anyone trying to aggressively talk to me about politics in real life, just online. And that is hardly a MA-specific thing, it's an internet thing.
