Hi @janiko! Actually I was born in Texas but I live over in Florida for now. I would consider Texas a "safe" state, like Florida as well, in that these two states support the Second Amendment of our Constitution - asserting that ALL citizens have the human and legal right (in these states) to protect and defend yourself, your loved ones, and your property from those who would threaten to take this away from you. These states, among others, have laws defending rights to purchase, and carry self-defense weapons.
Now don't get me wrong. I was in a war (VN), and I abhor war and violence as a means of resolving disputes. BUT, I do not believe people should be made victims because their governments restrict and hamper their ability to defend themselves as a last resort against violence inflicted upon them.
People who care nothing for YOUR safety, your right not to get robbed, and your right to live peaceably, are able to use weapons in the commission of crimes against the unwary and innocent . Being able to protect yourself, your family and those you care for, PREVENTS these criminals from attacking without fear of reprisals.
I hope this answers your question about safety. As to overcrowding, I suggest you would have to visit these places you are interested in and see for yourself if it is overcrowded more than you would like. Many places are overcrowded these days, but there are many areas in most states in the U.S. that have wide-open spaces in which to live.
Take time to travel and see for yourself! Best of luck and be safe! 😉
