The Tell

When instead of welcoming open debate
certain dogmas demand
that any such threat be outright banned
              or firmly deterred from taking place

and when censorship of any expression
that calls into question  said dogmas' tenets
is a free-speech-and-thought-throttling given
— as if squelching dissent were essential
              to protect the cred of the system —

you may safely bet  the proverbial bundle
that under even the meekest  mildest scrutiny
       the tenets in question will rapidly crumble.
