Genuine question for all of you

Why do you hate people who move here from another state so much? I grew up in Missouri and frequently spent my summers here with my grandparents growing up. We used to go camping and fishing all the time and some of my best childhood memories are here in Colorado. I recently moved from Florida where I lived for a couple of years and I never experienced the vitriol that some of you guys spew non stop. It’s the freaking US, you guys need to chill. This whole ‘native’ thing is weird and creepy. Make me understand your aversion to ‘non natives’ because I really don’t get it.
