Respect doesn't require agreement
Kenny Rogers sang*:
"... know when to hold 'em
Know when to walk away
And know when to run"
While he's singing about poker and cards, the same can apply to words. Not agreeing can be one of the best (and often fun) ways to learn and grow. If parties aren't approaching the conversation with mutual respect, it is ok to leave. You are always worth respect.
