I have found - if you're unapologetically yourself - 'bad' people just bugger off?
An example I'll give is - I used to be fat and didn't like this.. I lost weight to become a normal weight person. A few people really didn't like it and obviously wanted to keep me in my place.
I've used the fat/weight loss example. But I've also seen this phenomenon with regard to other things. You may have your own version.
