I'm the kind of person who does not take sides. Not just politically, but in any debate, dispute, argument, etc. For example, Democrat vs. Republican, or Trump vs. Clinton, or Chevy vs. Ford, or Mom vs. Dad (in an argument), etc. I stay in the middle of such situations. Sure, I choose bits and pieces which I agree with from each side, but I also acknowledge that each side will have its pros and cons.
What word (or phrase) can one be labeled to describe this state of mind?
I can't choose a side because I'm a [WORD], I stay neutral.
The only word that comes to mind is "neutralist", but I made that word up.
