I used to be very opinionated but over the years I've mellowed. Particularly after the DX when I started to see how a lot of the crap I'd experienced could have been largely down to misunderstanding.
I also got a lot of help from alternativist cultures - they seemed to have a very non-judgemental ethos, and I liked that because of course it meant that they wouldn't judge me too glibly Typical example was when we were in a taxi and the driver was being quite rude to us......for two pins I'd have bawled him out and spent the rest of my life telling people about the horrible taxi driver and what a scumbag he was. But one guy said "it's OK, he's probably just having a bad day - let's give him a tip and maybe that'll convince him that the world isn't so bad." So we did that, and the driver did seem to mellow a little. I felt I'd kind of grown up that day.
I guess my poiint is that strong opinions tend to lead to destructive conflicts.
I used to be very opinionated about women's revealing clothes, and beleived in a very concrete way that such women were worthless bimbos. But I kept thinking, and eventually realised that for a lot of them, it hadn't been a deliberate choice to fly in the face of what I would call decency, it was just that they'd been brought up with different values, and that all I could do was to express my own preference, and to own that, instead of trying to insist it was the only way of seeing it.
I think that once you start to own your opinions and preferences, instead of projecting them out onto the whole world as The Truth, then you've taken a very important step towards enlightenment. It helps to avoid listening to politicians - they set a dreadful example because they're always trying to pretend they've got the answers, they call this bigotry "resolute statesmanship" and they seem to do very well out of it. It might make a lucrative career but socially it's a disaster. We do not need resolute statesmen, we need thoughtful people who know that their opinion is not everything - but that's just my opinion.
