Any lifts or reflex exercises that will help me defend myself from knife attacks coming from behind me?

I'm not gonna lie. Why are whites so soft? I'm am Indian living in America, and my Instagram algorithm is full of black on white violence from both America and Europe. All the white dudes that comment on these posts just say, "enough is enough!", or "how long will this go on!?". I get that they can't physically do anything to the people in the post, but at the least you'd think they would call for a beating or death for the perpetrator. Some white professor lady gets killed in a park, "The usual suspects".

What an eventful week it's been. From the Ukraine girl getting stabbed, to the Indian guy getting beheaded, and then the the cherry on top, Charlie Kirk getting throated. Oh well, time to wage slave tommorow.

As a spokesman for the incel community, knowing that none of us would have had a chance with her romantically, should we care about this event?
