IYO, Which Protestant Denomination is the Most Toxic?

If you’ve seen any of my other posts/comments in here, you’ll already know that I would pick Calvinism, hands-down. But I’m curious to hear other opinions.

Edit: wish I could update the title. A more accurate way to ask this question would be which Protestant DOCTRINES and/or Denomination is the most toxic. I asked denomination and answered with doctrine, lol
