Yeah,. racial abuse, sexual harassment, open discrimination against homosexuals, these are all things that used to be commonplace back in the day. As a straight white male, you probably saw nothing wrong with those things but I'm willing to bet that the subjects of those actions were really not OK with it at all. Hell, smoking in the office used to be commonplace, that doesn't mean you should be lighting up now.
So, do you want all of us over 40 to grovel and apologise for being born and living when we did?
Maybe you should be grateful that the vast majority of us recognised the injustices and put in place a culture which no longer tolerates such behaviour.
