Staying in your lane is important, but I feel like a balance needs to be reached. I understand how frustrating it is to have people who have nothing to do with an issue or country or area talk about it, but sometimes they have a whole new perspective to offer. Something that you never thought of.
I learned this while working ina volunteer group. There was a girl with vastly diff perpectives than mine, and thus she was able to see things I and the others with my background couldn't.
