Go to this chart (https://en.wikipedia.org/wiki/List_of_mass_shootings_in_the_United_States), scroll down, you won't see a Texas shooting until 2019, plenty of blue states ahead of Texas though. Once more I'll ask, why do you find it necessary to single out Texas?
Don't like that source? Go here (https://www.cdc.gov/nchs/pressroom/sosmap/firearm_mortality/firearm.htm), arrange the data table by death rate, highest to lowest - Texas is 26th, in the lower half of all states. Once more I'll ask, why do you find it necessary to single out Texas?
