Interesting question......
Going by my own experience with men, I'd probably be a candidate to be exceptionally wary of them and harbour some hate for them as a species - but that said, I'd be very lonely and bitter if that was the case.
I try to treat everyone as an individual but some men do display the same twattish behaviour and attitudes and it is alot to do with environment and upbringing I think.
We hopefully learn from repeated mistakes - so then if a similar pattern we have expperienced before comes up it can evoke a flight and / or fight response, and if there are traumatic memories attached then fear easily translates to hate.
I have seen alot of LTB threads, but often it does appear to be justified. i have also seen threads where women querying quite abysmal behaviour are advised that their DP or whoever is probably stressed, depressed, unwell, has dementia etc etc. and it is only if these things can be ruled out will the poster be believed. Would it be the same if the question had been posed by a man? Until I see that thread, I wouldn't like to speculate.
My ex DH caused the end of our marriage by doing something so spectacularly stupid I ended up sectioned.While at "The Spa", my trust completely shattered and actually fearful he had no sense of boundaries whatsoever, I told him I wanted a divorce. His response was that we'd have to have a family meeting to decide that. My response was that our marriage was not a committee matter and I was not over-reacting in the very specific circumstances. Nine years later I still speak to mutual acquaintances who will minimise on his behalf because I have rebuilt my life, have a new DP and am ok. As if that somehow cancels out the trauma and angst I have suffered and that still occasionally puts me on the back foot and has coloured my new relationship. Fortunately my new DP will talk about those occasions and I feel secure enough to work through it all. The fact that he was obviously not in his right mind is used as an excuse...... my psychotic break was regarded as something of a self indulgence by some and I was expected to get my shit together and carry on, while he got MH treatment and support - allegedly - there is some confusion around this point and obviously it is none of my business..... hey ho.
So occasionally I feel hateful towards twattish men, and towards unreasonable women. Every situation is different.
