Like I said, be mad if you want. Doesn't change anything. His vote still counts the same as mine and everybody else's. You still live in a world where you need that guy to be on your side. You can either shout at the wind that the world isn't the way you think it should be or figure out how to improve the world that is actually in front of you.
Absolute fucking shitheaded moron fuck who’s screwed us all to ingratiate himself with nazis.
Guy isn't trying to ingratiate himself with anybody. He just told you what he was trying to do—make the world better for himself and his family. In particular, he wants to spend less on groceries. Low information voters might not be able to connect the dots between supreme court nominations, monetary policy, and broad economic trends, but they will unfailingly notice they're spending 20% more on groceries than they did four years ago. You want to point out that it's not the Democrats fault inflation ballooned out of control? I'm right there with you. I voted that way in Pennsylvania. That guy doesn't care. He voted the other way because he wants cheaper groceries and as far as he can tell, Democrats didn't get it done. Calling him a moron and Nazi ally isn't going to change that.
Anywhere from very important to not important at all, depending on your specific job.
There is some good news though, you've been lied to about sucking at math. Whether by yourself or other people I do not know, but the education research I have seen has been pretty clear that the main difference between people of normal intelligence who are 'good at math' and those 'bad at math' is how long they're willing to work on a problem to ensure the correct answer before moving on.
I know 'try harder' sucks as an answer but it's the best one I know of and at least in this case will actually make a difference.
