the.com/firebrand

Someone who treats every room like it needs more heat and less consensus.

means A person who stirs up passionate, often rebellious feeling — through speech or action — and is literally or figuratively always lighting a fire under something.

from Originally just a piece of burning wood — a 'brand' (from Old English 'brand/brond,' meaning fire or flame) that's on fire. By the 1500s English speakers started using 'firebrand' for a person who kindles unrest or passion the way a burning stick kindles tinder — someone who sets things ablaze with words instead of flame.
