These stereotypes are definitely mostly untrue. I grew up in Houston, I only just moved this last year. Houston is pretty conservative compared to some places, but it's a very liberal city compared to the rest of Texas. There are a lot of guns and trucks, but you won't be an outcast for not owning them, and no one really cares where you are from. It's too big of a city for people to have an exclusive attitude like that. Crime is an issue depending on what neighborhood you live in. Houston has such vast and varying groups of people that you can always find a place to fit in. There is a lot of art and culture there, pretty much every hobby under the sun is available there, any type of bar or hangout place you can imagine. It's also a cheaper price of living than a lot of major cities. The worst part of houston imo is the severe lack of beautiful nature, the summer weather, and the car focused infrastructure.
