This is a common misconception about what it means to be against political extremes.

It does not mean "both sides have a point".

It does not mean "both sides" are equally bad.

It does not even mean that there are necessarily two sides.

The term "centrist" is used to imply and reinforce these misconceptions, encouraging people toward extremes. When you see things in black and white, of course everything is a straight line from good to evil (with you at the far end of good), so if someone only partially agrees with you, they're in the "center" and that much closer to Hitler than you. It's hard to step outside of this fantasy. But I'll try to help you.

Imagine the following dialogue.

A: "Are you Hindu or Muslim?"

B: "Neither. I'm an atheist."

A: "Oh, so you are torn between Vishnu and Muhammad."

And yes, one of the political parties is significantly more deranged than the other right now. You don't need to be extreme to see that and it is possible to vote for the more reasonable party without drinking their kool-aid.
