They don't even have to actually spoil the barrel. Since dramatic events stand out in the human mind, it's possible for a few bad actors to completely change people's perception of groups or their place in society.

This is part of the reason why it's so hard for privileged groups to understand how minorities see things and vice-versa. What's a dramatic, salient event for one group is not so much for the other.
