I have a 'friend' who doesn't give up.
Several aggressive 'signals' i.e. social media photos showing 'allegiance' to 'them'
and outright arguments with me in the past, once even storming off,
and yet the invitations to socialize continue.
I feel it's toxic, even emotionally sick, to continue this and am going to take a firm line.

I just declined an engagement from my previous social-cultural milieu where I was a medium-sized fish
in a small pond - now, by my choice to ghost the 'mandate quislings' i.e. fellow fish, I am no fish
in no pond. So it goes.
