Attivista vs. militante
While both attivista and militante refer to someone engaged in supporting a cause, the difference lies in the nature of their commitment and organizational ties. Attivista is a broad term for anyone promoting change, whereas militante implies a stricter, disciplined allegiance to a specific political party or ideology.
Attivista
B1This is the most general term for an activist. An attivista is anyone who takes action to bring about political, social, or environmental change. It focuses on the action taken for a specific cause (like human rights or the environment) rather than loyalty to a specific group hierarchy.
L'attivista ha organizzato una raccolta fondi per il canile locale.
(The activist organized a fundraiser for the local dog shelter.)

(Greta Thunberg is a famous climate activist.)
Gli attivisti hanno raccolto migliaia di firme per la petizione.
(The activists collected thousands of signatures for the petition.)
Essere un attivista significa non rimanere indifferenti alle ingiustizie.
(Being an activist means not remaining indifferent to injustices.)
Militante
B2Derived from military terminology, a militante is someone who is an active, often registered, member of a political party or organization. It suggests a high level of discipline, ideological rigidity, and continuity. While it translates to militant, in Italian it emphasizes intense dedication and membership rather than necessarily suggesting violence.

(My grandfather was a militant of the party for fifty years.)
I militanti hanno distribuito volantini elettorali tutto il giorno.

Summary
In short, use attivista for general social or environmental engagement where the focus is on the cause. Use militante when referring to dedicated, long-term members of political parties or structured organizations who follow a specific line of thought or discipline.
