It feels like a snub when Facebook friends of higher social status ignore my messages to them when I know they’ve read them. I don’t tolerate insults to my class or gender in my daily life & see no reason to tolerate them on social media. If there is one sensitivity & commitment I have in spades, it is to equality in human relationships. I would not be the one to mess with on that score. Women of a certain age don’t take crap in place of respect.
