The truth is the left's politics are driven by resentment--"those people have more money than us--not fair--get them!"
When the government takes your property by force, which is what excessive taxation and redistribution is, it's tyranny.
And the right's politics are driven by entitlement - "let's take advantage of workers and pay off lawmakers so as to enrich ourselves as much as possible and screw everyone else."
So taxation itself is not tyranny, just excessive taxation? And I guess you're the arbiter of what constitutes excessive.
