A single-sided focus on the negative aspects of western society and its actions combined with a Rousseau-inspired 'noble savage' attitude towards non-western societies is hating the west and is most likely what the grandparent poster refers to. All the vices attributable to western society - slavery, colonialism, brutality, sexism and all the other -isms - can also be attributed to other societies but these go mostly unmentioned or are mentioned in passing without leaving a mark while they are portrayed as being essential elements of western cultures.
