At their essence, love are fear are irrational.
Unwavering and unconditional love is irrational because it means one continues to support and cherish people (and other things) no matter how much shit and pain said people (or things) cause. It’s smiling at danger and pain. Unyielding and incessant fear is irrational because it means one continues to hide or run despite there being there being no signs of danger. It’s staying inside on a sunny, cloudless day because one is afraid of being struck by lightning.
