As for the Nazi comments:
What would YOU call an ideology/political movement in which:
1. The enforcement of lockstep adherence to ideological orthodoxy is the PRIMARY concern in all endeavors.
2. That when an individual is found lacking in terms of orthodoxy, or he/she sould poiint out a logical contradiction in that orthodoxy, he/she must be personally destroyed by a campaign of slander and/or personal attacks.
3. Where the ideology in question is believed to have the imprimitur of the Almighty.
4. Where the followers of said orthodoxy, when cornered logically and rhetorically, will resort to the immediate and vicious castigation of the person who exposed them.
5.Which continually harkens back to the folklore of the glorious past and which holds it up as an ideal to be re-achieved, right NOW, at the expense of progress.
6. That believes that human nature can be controlled by passing laws and then ruthlessly enforcing them, and which believes that laws passed by elected legislatures with the support of the voters (as in NY States gun laws, for example) are a threat to liberty when they infringe upon a behavior they DO approve of. This DESPITE the fact that such laws were duly created and voted upon by democratic means.
7. That certain social and political movements should be criminalized, their practitioners criminalized, and their rights systematically stripped in order to "save" the country? Their (the Movement's)rights, of course, will be upheld to the Nth degree.
8. Regularly characterizes those who disagree with them (and worse, can disagree with them in words with more than four letters in them) as "the enemy".
9. Regularly tosses around political characterizations which are patently false and deliberately misconstrued (i.e. as in the use of the word "liberal" to mean something other than what it really does).
10. Is more than ready to jump all over it's oppositions contradictions, but which conspicuously ignores it's own.
11. Regularly re-writes history so that it's heroes are always presented as super-human titans who have been deliberately tarred and distorted by their enemies.
12. Believes that, ultimately, it will have to achieve it's aims by outright force of arms (hence, the skewed reading and interpretation of, and the inordinate emphasis placed upon, the 2nd Amendment), when it finally loses at the ballot box.
Sounds an awful lot like fascism to me.
