I’ve noticed that middle-class attitudes prevail almost exclusively, particularly when opinions are sought. This is most noticeable in threads about child-rearing, attitudes to the workplace, attitudes to romance/sex/dating, schooling/education, friendship and the like. There appears to be more variety in political discussions but still, middle-of-the-road attitudes dominate there as well.
There have been a few threads where the middle-class view offers up an almost bullying insistance on conformity to middle-class values. I’m thinking of one thread wherein a single mother sought advice about schooling for her son, and another where (tongue-in-cheek, for certain) a hand of friendship was extended but spurned because the hand was attached to ‘trailer park trash’ with an abusive partner.
I’m not taking the moral high ground here, it just seems to me that exclusion of sets of values that cannot be grouped into that amorphous category known as middle-class is either embracing ignorance, or, worse yet, posturing that only middle-class knowledge is valid knowledge - all other knowledge and experience is logically inconsequently dismissed as ignorant.
