I think everyone being more aware of their behaviour and the behaviour of others around them is a start.
It doesn’t remove the issue and there are other things that are needed to be done but just being conscious of how other people might feel is an easy way to start.
I remember being told at school when we were 12 or 13 how old people might be intimidated by us even if we weren’t a threat, I think just being conscious of stuff like that can go a long way to helping.
