First of all, Wikipedia is useless for definitions of words that are in the middle of active political debate. You completely ignored the definition I gave you (which is from an impartial source [1]) in favor of one you prefer, from a wiki.
Setting that aside, you will see the that the citation for that definition [2] basically underscores the ambiguity of the term:
> Political scientists have outlined elaborated typologies of authoritarianism, from which it is not easy to draw a generally accepted definition; it seems that its main features are the non-acceptance of conflict and plurality as normal elements of politics, the will to preserve the status quo and prevent change by keeping all political dynamics under close control by a strong central power, and lastly, the erosion of the rule of law, the division of powers, and democratic voting procedures.
I challenge you to defend the proposition that the current administration is attempting to "prevent change by keeping all political dynamics under close control by a strong central power", while simultaneously clearly acting to undermine many parts of said authority. There are actions by every administration that appear to be "authoritarian" when taken in isolation.
The parts about erosion of rule of law, etc. are clearly also applied to the current administration, but again, are mostly debatable -- these EOs are either within the power of the executive under current law, or they're overturned by the courts. I openly grant that our legislative branch has been on a 50+ year mission to abdicate responsibility to the executive, but that's neither exclusive to the current administration, nor is it "authoritarianism" to use the authorities granted to you under the law, and again, it's not unique for US administrations to overstep the law and be pulled back by the judicial.
