A fair enough opinion, and a worthy discussion. But this particular issue of Trump’s Twitter suspension is clearly about not giving delusional lunatics more fodder for their actions, rather than silencing Trump.
Edit: I’m not siding with or against Twitter here. Whether their decision was wise or not certainly needs to be discussed. I’m just pointing out that “silencing the lunatic in the White House” isn’t the only potential explanation for their suspension of Trump’s account.
