While Capricorns love to (and usually can) win an argument, they actually dislike conflict and will usually avoid any sort of debate that might get heated. They just don't have time for other people's nonsense!
But, if someone messes with a belief, cause, or personal attribute they hold dear, watch out! The stubborn, guarded Goat will prove you wrong every time.
And if they are lied to, their fighting spirit (intellectually, verbally - they are not the physically aggressive kind) comes out full throttle!
Bottom line: yes, Cappies are usually right when they put their two cents into an argument, but only if it pushes their buttons.
