Southern legislators succeeded in getting a federal "gag rule" because they feared that walker's appeal and other aboloitionist writing would inspire slave revolts. which of the following justified that fear? gabriel prosier's rebellion turners rebellion bleeding kansas john browns raid

I believe the answer is turners rebellion
turners rebellion rebellion was regarded as the most devastating Slave's rebellion in united states history.
Since around 1/3 of the southern population were slaves, the white citizens were living in fear and tried to pass the gag rule to make public encouragement for rebellion became illegal.

I don’t think is the right place to be looking for friends..
