It's a strategy and war game podcast focusing on a single game per episode. At least some of the hosts are leftists but I don't know how much that's obvious from the content of the show itself (I only listen to an occasional episode since it's not usually my genre). I think OldeWolfe is insulting the hosts here, not agreeing with them, as one of the hosts is a trans woman.
I don't know if this will help you but I started getting far fewer and far milder canker sores when I stopped using toothpaste with sodium lauryl sulfate. There's research suggesting a casual link, at least for some people who are SLS sensitive: https://pubmed.ncbi.nlm.nih.gov/7825393/
It's listed as an "inactive ingredient" on toothpaste boxes but usually not on the tubes themselves.
