By referring to Thesaurus.com, you can see that you could describe an opinionated person asadamant, arbitrary, assertive, biased, bigoted, bossy, bullheaded, cocksure, cocky, conceited, dictatorial, doctrinaire, dogmatic, hard-line, high-handed, inflexible, intransigent, locked in, obdurate, obstinate, one-sided, oracular, overbearing, pigheaded, positive, pragmatic, pragmatical, prejudiced, self-assertive, set in stone, set-on, single-minded, stubborn, tilted, uncompromising, unyielding, or weighted.

If they are also argumentative you could say that they are belligerent, combative, contentious, contrary, controversial, disputatious, factious, fire-eating, having a chip on their shoulder, opinionated, pugnacious, quarrelsome, salty, scrappy, spiky, or touchy.
