You need to start keeping a bound diary, one with a permanent binding where pages can’t be removed. Write down everything anyone says to you that offends you, or threatens you...dates, times, names, etc. If you observe other Conservative co-workers being admonished, keep a record of that too. Keep the diary with you at all times, and keep it up-to-date. You may need it if you are ever disciplined or fired. I was told to do this by a lawyer many years ago. My case was different, and I never got fired, but documentation like this can be used in a court of law if ever needed...even Civil Rights cases. Protect yourself.
In the long run, if they want you out they can get most anyone in a year or two.

I’ve heard of that but also that you should number the pages to make it that much more valid.
