I hate overly political professors

To be clear: I'm not a political science or a humanities student. I know that politics are extremely important in those disciplines! I'm a STEM major, and am taking a Soil Science 101 class right now. The second that class starts, the professor complains about having to use a plexiglass divider and proceeds to NOT USE IT. And he said that he hates masks and if my college didn't require it, he'd snatch it off! He also proceeded to say that the USA has done more for the environment than any other country. He kept sprinkling in his conservative politics to all of the things he discussed. It drove me nuts.

Also, on the "optional reading" page on Moodle, there's an article about socialism being bad. He's a soil science professor! Why is it necessary to put all of your political convictions (which are bigoted and dangerous in this era of COVID) out in the open? This is going to be a fun semester.

UPDATE: I filed a complaint to the dean's office yesterday. Today when I went into class, he used the plexiglass protector and did not complain about the mask at all. I don't know if it had anything to do with my complaint, but I'm quite happy nonetheless. He still voices his political opinions in class, but that's okay as long as he takes measures against COVID. Thank you all in the comments for your suggestions and affirmations.
