Who is the Texas school shooter? What we know

At what point are people going to understand that when they see social media posts like that they should notify the police.

This could have been prevented. One entry point, locked and with a armed guard is a sad reality we live in today with the destruction of a once great culture. One where we were all equal under the law, where work and motherhood was respected, where parents brought up children and people had respect for the law and law enforcement.
Sure, nothing was ever perfect. But that is no excuse for this large central government, sub-cultures, open borders and hatred for a nation where one can become a Supreme Court Justice, POTUS or a 4 Star General if you try. Nope. We can't have that. Let's destroy the family, allow mental issues to flourish and create division until we break apart.
Our society has cursed itself. This post of yours SFC is one example of that.
