They say that the Democrats media is able to gaslight their ignorant followers. How true is that, and is the fact that Democrats have echoed that Jan 6th was worse than 9/11 or Pearl Harbor proof of that, via gaslighting their ignorant followers?

The basic answer is that you cross-multiply the values in each factor:

The more direct answer is to look at a rectangle with sides of n + 1 and n - 1, let’s go with n = 2

Move the nub up to the top:

Trump's huge bill includes immediate gift for layoff-ridden Bay Area tech - SFGATE

And you are left with almost a square. One less than the square of side n.

n^2 - n + n - 1

Do you believe that it is right that one Federal judge can block a President's decisions?

n^2 - 1

If you cut off the end of that rectangle, you make it smaller, 2 * 3 and a separate nub of size 1 * 2

So, that’s a rectangle with sides 2 and 4.

Hamas uses 100,000 human shields and no one cares. Israel straps one wounded terrorist to a Jeep to transport him to medical facilities and the world cries. What gives?
