As a not-Texan, almost all of what I hear about Texas is oil, conservatism, failed power systems during winter, anti-abortion-rights, and using immigrants as political theater by sending them to DC/NY. I don't know that the disdain is unexpected given the political leaning of people working in technology.
I get most of my national news from NPR. What news am I missing about Texas? I guess I forgot the Uvalde school shooting police response in my list.
I do hear bad things about California - homelessness, drug use, lots of petty theft that doesn't get prosecuted, ridiculously expensive housing, NIMBYs - but that's unrelated.
I'd better not get too involved in this because it's ugly politics nonsense, but it's easy enough to find criticisms of California for its power grid, leftism, pro-abortion-rights (which is obviously seen as a bad thing by many people), and political use of immigrants.
