Isn't this the exact reason Americans give for having their right to bear arms? Why is there not an armed revolution against the clearly corrupt government?

Because that's ridiculous and exactly what foreign adversaries would love to see as a result of the currently tense political environment.

Plus, violent protesters almost never come out looking good. Any violence coming from the left would just entrench the powers of the right.

There are a few exceptions, like the revolutionary war. But, that's a time when American people were separated by great distance from its governing body. Revolution doesn't work when you're connected by land. Some foreign power would just take advantage of our weakness, and all Americans would lose.

We need to find a way to work together.

People usually need to anticipate a lot of hardship/uncertainty before they're willing to get into a war. De-prioritizing Netflix traffic doesn't really fit the bill.

These issues are much more sophisticated than many people appreciate. Democrat and Republican, all FCC commissioners have a telecom industry background, which causes everyone to posit that they have a bias toward their former employers. But how can you be expected to regulate the telecom industry if you have no idea how it works? How do you establish that someone knows what they're doing if they don't have an industry background? There are a lot of complexities here.

That's why our system of checks and balances is so important; it puts clear constraints on the powers of each segment, making it so no segment can get too much control. FCC is an executive-branch enforcement body; it can only do what Congress allows it to do.

Congress is at the heart of the governmental ineffectualness in the US. Fixing Congress would take care of most of our other problems.
