The Texas shooter violated a multiplicity of gun laws. The suggestion that more gun laws would have prevented this act of unspeakable evil is unsupported, and the implication that those who oppose such laws are somehow in favor of mass shootings is morally reprehensible.
Nice thing about these days is, people are going to talk shit and judge regardless of what you do or how you do it. So you are as free as ever to just do whatever the hell you want and not worry about it at all.
