The towns that are "up island" (to the left, Aquinnah, Chilmark, West Tisbury) are the "super wealthy" areas with private beaches and palatial residences. This is where JFK jr crashed (and had a home). As a general rule, these towns are peopled with the Karen-like leftists - when I visited in 2020, there were obnoxious passive-aggressive signs telling vacationers to quarantine for 14 days before wandering about. This summarizes this lot pretty well.
As you go "down island" to Vineyard Haven, Edgartown (home of Obama's palace) and especially Oak Bluffs, it gets a little more normal. It's more commercial, more touristy, and the locals aren't as obnoxious. When I was there in 2020 and asked the locals and business owners about masks, they basically said "yeah, well, you're supposed to but if nobody says anything do what you want and I don't care." The waitresses were unhappy about the masks because they were suffocating while carrying trays of food.
That's said, the Island as a whole went 78% for Bidet - someone scolded me from a car for being unmasked WHILE WALKING and I replied "thanks Karen."
Amity, as you know, means "friendship."
But Martha's Vineyard means "hypocrite".
The flip side, is that one-fifth of the Island voted for Trump. Indeed, one guy on Circuit Ave in Oak Bluffs sells cool shirts, including an anti-Ted Kennedy shirt with an Oldsmobile under water! I suspect there were MANY year-rounders grinning and cheering about the hypocracy on display.
