Sheeple

/SHēp(ə)l/
noun/
definition:

an individual or group, compared to sheep in being docile, foolish and easily led, proverbial for its tendency to follow others in the flock. Observed to often echo statements and ideologies void of verification, enduring rhetoric fed to them. Often in denial that the propaganda is not their own nor sincere.

Most of the supporters of that cause are not familiar with the details, they are just sheeple.
