You're right, I am more angry at Greg Abbott than I am the shooter. Part of it is that despite my best efforts to prevent this from happening, I'm a bit desensitized to these mass shootings. I'm mostly more angry at Abbott because he's a xenophobic crap stain that has policy positions that has led to Texas averaging one mass shooting a week and 6,000 gun deaths a year. Instead of doing something to fix issue of thousands of Texas citizens dying at the hands of guns, he's shitposting about immigration, despite the fact that not all the victims were illegal, as if that matters a single bit.
So yeah, you're right.
Now you want to tell me why you care so much about the immigration status of these people? Texas has actively allowed all citizens, legal or otherwise, to carry weapons used to murder others.
