ALL OR NONE THINKING

Some personalities tend to perceive things in terms of black-and-white or all-or-none. They might take the position that if they can't have everything they ask for, they won't accept anything at all.
If someone doesn't agree with everything they say, they feel unaccepted and feel they are not being valued or listened to in any way.
If they don't see themselves as completely on top of things and in total control, they will view their circumstance as being on the bottom and the victim of someone else's oppression.

This all-or-none and black-and-white type of thinking is what prompts these personalities' behavior of carrying things to extremes. In other words, extreme thinking leads to extreme behaviors. Such thinking interferes with a person's ability to develop any sense of moderation. It also promotes an uncompromising attitude that causes untold problems in relationships.

Dealing with individuals prone to extreme thinking is extremely difficult. You try to reach some amicable middle ground with them, but it's next to impossible. Somehow you always end up feeling like "it's their way or no way." There's no room for negotiation or compromise, and it leaves you feeling like there's no way to interact.

Extreme thinking and the uncompromising attitude promoted by it are at the root of the stubborn and unyielding behaviors that these personalities display. And these can easily decimate a relationship. A person who thinks in extremes will not be prone to give ground, and giving some ground is essential to reaching compromises in life's many conflicts.
