>>10937412He knows too much of them and would like to know less. 50% of them he would like to know less, such that his level of knowledge of a person in that 50% is currently x =< 0.5 and he would prefer that level of knowledge to be equal to or below 2x-1. Since he knows them too much, this represents a significant amount of how much less he would like to know them.
His dislike of them is mostly deserved. Less than 50% of them deserve to be disliked by him less, such that if he liked them at a level of y =< 0.5, they deserve to be liked at a level of at least 2y. However since he already likes them so little, what they deserve is hardly a step up from his opinion of them.
