How to say "anarchist" in Japanese

• アナーキスト
  nounThe katakana rendering of 'anarchist': a person who rejects the state or authority. Like the English word, it can be used loosely of anyone who defies rules, and it appears chiefly in political discussion.
• 無政府主義者むせいふしゅぎしゃ
  nounThe kanji term, literally 'person of no-government-ism': an adherent of anarchism as a political doctrine. It fits writing on political thought and the history of the movement, where the ideology itself is the topic.

Both denote a believer in anarchism: 「アナーキスト」 is the direct loanword, also usable loosely for a rule-defier, while 無政府主義者 is the kanji term foregrounding the ideology, at home in political and historical writing.
