You're right, it is depressing, twindad
The thing is, though, I'm not 'aware' or 'wary' of men because I read the DM; or because of some sensationalist reporting on the BBc; or because of a FB item on my newsfeed; or something I read on Twitter; or some gossip at work because someone's next door neighbour knows someone who's aunt's friend's daughter heard something in the playground; or because of something a radicalised group has announced/or done...
I have a wariness of men because of something that has been happening to me on a frequent basis since I was 9 years old by ordinary men who are someone's boyfriend/husband/brother/son/cousin/nephew/uncle. Who are all ages and all socio economic groups and all look different. I'm nearly 40. It's happened at work, it's happened when I've been out with my friends, it's happened in the car park at the supermarket, the cinema, on public transport, in pubs, at train stations.
You don't like reading about it here because there are several hundred posts that have made it bit clearer to you. And that's understandable, and a good thing! But please don't tell us now, that on top of everything else, we're just being sexist!
We know that not all men are like this. But then we don't know which strange dog will bite us either. So we are wary of all of them.
If men don't like the fact that the behaviour of other men makes women wary of men, then I'd suggest that the solution lies is tackling the behaviour of these men, rather than making that the fault of women, too.
