You aren't expected to be perfect to expect acceptance.
Can I phrase it this way:
If you don't have respect, no matter what group you belong to, you have to have an understanding of how to win respect and change stereotyped and inaccurate perceptions.
Imagine the scenario in the playground. A new girl comes along and she don't know anyone. She's an outsider. She not going to get friends by standing in the middle of the playground and shouting "why does no one play with me" and just generally slagging everyone else off.
She might be right that the kids look at her funny and make judgments cos she's wearing the wrong clothes and is uncool and they don't want to hang out with her cos they are afraid of what the other kids might say. It might be simply because they are a bit shy or unsure of her as they don't really know what to expect as they've heard that people who come from X Town eat pet dogs and cats.
But the other kids aren't going to make the effort or break from the main groups because she stands there accusing them of being cat killers simply because they are from Y Town. It just pisses people off and makes them not want to engage or change their perceptions.
It might not be fair, but its a basic understanding of knowing how you can change people opinions.
If you act in a way that alienates others from you, not only does it isolate you, but it also has the effect that the next new girl gets treated in the same way but with even more lack of willingness to try include her, because the kids all think "you remember the last new girl". And thats before they know anything about the second new girl at all. Conversely, if the first encounter had been a positive one, maybe the kids in the playground might rush up to the second new kid with open arms.
Ultimately, rightly or wrongly, how the outsider acts has an enormous influence on the main group, and it is up to them to realise this and to actually make the effort to engage with the group with a positive approach rather than a wholly negative one from the word go.
You can change opinions and people will be more responsive if you take a positive approach. Political leaders and those with influence within their community need to be more aware of this than anyone else. Julie Bindel fails miserably at this.
Deliberate separatism and deliberate slagging off others, reaps what it sows and frankly just makes you look like you've got a huge chip on your shoulder to anyone else outside the community.
