Militant vs. activiste
While both militant and activiste are translated as activist in English, they carry different connotations in French. Militant is the standard, positive term for organized commitment, whereas activiste can imply radicalism, direct action, or simply be a result of English influence.
Militant
B1This is the most common and generally positive term. It refers to a person deeply involved in a specific cause, typically as an active member of a political party, a trade union, or an NGO. It implies a structured, long-term commitment and often involves grassroots work like distributing flyers or attending meetings.

(He has been an activist in the Socialist Party for ten years.)

(The activists organized a public meeting.)

(My mother is a highly respected union activist.)

(She remains a committed animal rights activist.)
Activiste
B2This word focuses on action rather than membership. Traditionally, it has a slightly pejorative nuance in French, suggesting someone who favors direct action, disruption, or radical methods over debate. However, due to the influence of English, it is increasingly used in media to describe modern campaigners, especially in environmental or hacker groups.

Summary
Use militant for standard political, social, or union engagement involving volunteers and members. Use activiste when referring to people engaged in direct actions, disruptive protests, or when the context implies a focus on specific operations rather than organizational loyalty.
