Your original comment in response to the 1968 Vietnam protests stated "before we got all police-statey", which any reasonable reading would see it as implying we were not police-statey in 1968 and became so later. Dude posts about Kent State which happened in 1970 to show what makes them believe we were already police-statey around that time. How you manage to read that as saying things haven't gotten worse since 1970 is beyond me.
Edit: I'm not here to debate the definition of police state or whether we are one, I'm here to point out what is and isn't there in the actual comments
I support the right of clowns to strike for whatever reason
