I don't personally bother to enter debates online as generally I can't be arsed but I have several friends who are a similar age to me (early fifties) and I must admit we tend to look it!
Anyway I have noticed that they receive a lot of nasty, comments about their being old, stupid old bag, old witch etc if their opinions aren't popular.
I just feel that ageism is tolerated by society far more than other -isms.
Is it just me?
