I just listened to the podcast and it is both a complex and simple issue. It is complex in that she is deeply into pinball and that it forms a part of her identity. She is big into and proud of being a female and of another race, which she should. She seems hurt that she and other diverse voices are not included in the TPN. I don't know if she was asked, not asked, whatever, but that is her perspective. Again, lots of complex emotions for her. Nobody has to understand or champion her point of view, but we should all acknowledge that it is her point of view. You can't tell people how to feel, and if you do, you are a dick.
On the simple side though, at the end of the day, this is not her podcast network. TPN is free to do whatever they want, and involve whomever they want. They are not the only game in town, and she and other podcasters are free to present whatever they want on their own, or to create their own syndicate.
Food for thought: I am not into the pinball "scene" and don't necessarily want to be into it. Just not my vibe. I don't play in tournaments, don't go to shows, and for me, pinball is a minor, minor distraction. I am sure that there are others like me who fit the bill and probably look at situations like this and say "whatever." For others, league night is a big part of their identity and represents significant things to them. Lauren seems to be in this camp. We don't have to empathize with her, but we can provide empathy.
