They that fear dissent may feel threatened by what it reveals. They that fear dissent may feel threatened that their own beliefs do not hold up to scrutiny.
For years, the corporatist media have derided what they describe as "Divided Dems." As if fealty to authority is to be desired. Some may indeed believe that fealty to authority is to be desired. Depending on who is that moment's authority.
To repeat something I wrote less than two weeks ago:
It would be irresponsible for responsible Democrats not to make their voices heard. It would be irresponsible for responsible Democrats not to be very clear about what they consider to be unacceptable outcomes. It would be irresponsible for responsible Democrats not to continue to define what it means to be responsible Democrats. It is never wrong for Democrats to stand up for what is right.
Be wary of they that would suppress dissent. Consider their motives. Consider their means. Feel free to disagree. With them or me.
