On my Facebook-feed the other day (Globe and Mail article), someone unknown to me, commented: "I know you think you can speak for everyone because you are a old, white man, but really, you don't know what anyone else thinks or wants."

Three or four times recently a comment I have posted on the Globe's Facebook has been criticised this way, i.e. not by addressing the issue sensibly, but by an ad hominem attack on me for being a "white", "middle-aged" or "old" guy. (Obviously the commentator looked at my profile pic and judged what I said based on my skin colour, approx age, and maybe by the fact I can be seen enjoying a pint of beer). And, it's always been a female that has made these comments. 

Seems some females have a bee in their bonnet when "white" middle-aged men have an opinion. For some young women, being a "white", "middle-aged" man invalidates anything you have to say. This seems to be a new thing. It's pathetic.
