Your fundamental point is spot on - the left absolutely does use language to subvert culture and ultimately erode our basic freedoms.
So “transphobia” -———> communism, yeah, I can buy into that.
So “unviable tissue mass” -————> communism, same deal, along with scores of other games the left plays with words.
But “decimate” —————> communism - that one doesn’t really worry me.
However, I will agree with those who would prefer “devastate” or “obliterate” as much better terms - and not because that would make me any less of a tool (no offense taken).
Am I the only one who has fought Army Worms? Way back in my farming days we had an invasion of the buggers. They loved to feed off of smaller trees and your crop if you let them. They build webs in the trees and make colonies and stripped the leaves. We would spray the webs with kerosene and set them on fire. BBQ worms. It took about 2 yrs to get them all dead. They spread quickly all over the place.
