The very things you cited as differences are, in fact, supporting parallels.
The leadership (politicians) can be changed if we the people are willing to commit more resources (not just supporting the good candidates financially, but by voting and making ourselves heard every chance we get). I'm a youngin', so I'm kinda new to the political machine, so anyone have any suggestions as to what we can do other than sit on our @$$es typing?
Attending demonstrations against illegals so they have more than two dozen people would be a start.
