(Not sure if this is the right forum, but…)
To "apologize"means to express sorrow and remorse for something, to admit wrong-doing and to take responsibility, etc.
But to be an apologist for someone is to deny and justify, spin and stonewall on their behalf, which is the opposite of apologizing.
Or am I defining apologizing wrongly? Perhaps it means to try to talk your way out of a situation one way or another in order avoid punishment or condemnation.
Oh, and imflammable means flammable?
