The biggest threat to this country are white nationalists as stated by the FBI not tiktok. this is all a side show to say look over there -> look at the bad guys.
I have seen that and it is indeed very worrisome. I hope that sufficient resources are allocated to domestic counterterrorism and domestic counter-intelligence.

This has been a known thing since long before Timothy McVeigh, a Ryder truck and Oklahoma City in the mid 1990s. It has not been adequately addressed in domestic law enforcement.
