I sincerely don’t know to what degree Trump and his crew may change the US, and by the looks of other countries, it could be as extreme as silencing the opposition by force. Are there any efforts to protect dissent? Can this be planned for and successfully fought back before it becomes a problem? Do you have a different view entirely?
There is no “protecting dissent.” Dissent will be outlawed full stop. This will be done by crazy means to make it sound viable to the Constitution.
There will be several levels of organized means of dissent. You could say a “resistance”, an “underground”, and a “rebellion.”
The resistance will be collective acts to prevent the admin from doing whatever they want. You may have seen governors come out and say they will not let federal troops into their cities - they have the authority over state national guard to do this.
The underground: this will be quiet forms of dissent. Visiting family in other states to bring them birth control, or take them across state lines for “routine medical care.” They will circumvent policies without attraction of the authorities.
Rebellion. These will be insurgent actions risking life and limb to oppese enforcement efforts directly.
