Manifestante vs. contestatore
The Italian words manifestante and contestatore both refer to a protester or demonstrator, but they have distinct nuances. A manifestante is generally someone participating in an organized public demonstration, whereas a contestatore describes someone who actively rebels against or challenges a system, often with a more confrontational attitude.
Manifestante
The word manifestante refers to a person who takes part in a public rally, march, or demonstration. It is a neutral term that focuses on the physical act of gathering to express a collective opinion, demand rights, or show solidarity, usually in a peaceful and organized manner.

(A demonstrator raised a peaceful sign in front of the city hall.)

(The young demonstrator was handing out informative flyers to passersby.)

(No protester was injured during yesterday's march.)

(Every demonstrator wore a red shirt to show solidarity with the workers.)

Contestatore
The word contestatore describes an individual who systematically opposes, criticizes, or rebels against authority, traditional values, or a specific establishment. It carries a stronger, more confrontational, dissident, or anti-establishment connotation than a simple participant in a march.
Il contestatore ha rifiutato di abbassare la voce quando la sicurezza gli si è avvicinata.
(The protester refused to lower his voice when security approached him.)

Summary
In short, use manifestante to neutrally describe someone who physically joins a public gathering or march. Choose contestatore to describe someone who embodies a rebellious spirit, actively dissents, or challenges the status quo and authority.
