Has that been the experience of all the other corporate headquarters who have relocated to Texas? They have been legion, as I understand it.
Many corporations aren't infused with a hard left-liberal corporate culture. Most are merely politically correct at the executive level. Texas Normals are probably doing just fine in those companies.
Then there are companies that have a liberal corporate culture from the top, down. I believe Amazon to be such a company. Normals won't fare so well at a company like that. Many, if not most, will eventually be pushed out by subtle cultural pressures, while hiring practices will tend to favor bringing on those with the 'proper' sort of social views.
This stuff isn't rocket science. It's just human nature, and very predictable. It's a form of social discrimination no different than the racist hiring practices of a half century ago.
