I joined Facebook when it was still college students only. The next year it was available to everyone, and I dropped it maybe three years ago. I check it rarely, when I really need to get a hold of someone or get a hold of a charity/animal shelter.
My friends from high school, many of them, blocked me when I voiced my beliefs on my feed. I no longer have any contact with them, which is a shame; my Dad graduated from the same high school in 1973, and he still has his friends, despite political differences. The friends who blocked me are essentially Socialists; the rest of my friends, whom I see now, are right-Libertarians or Conservatives. One is an admitted Commie, but loves the second amendment. Go figure.
I have Twitter, but don’t use it. I don’t do Instagram, and definitely NOT TikTok.
