Using these fears based around emotional health symptoms to force people apart is just creating the 'mental health inquiry' where those without access to mental health resources are abandoned for their symptoms by everyone around them out of fear despite clawing for access to help. It's repulsive.
If youve ever found yourself making major life changes at the whim of a friend because 'this happened to someone I know' that is just them using their own prejudices to control you. That's all it is. Fear. That's why it's control.
Can you think of anyone else who wanted common people to fear each other over hypothetical scenarios? Do you understand now what the problem is?
Using ambiguous fear to control others is literal fascism. Those who use ambiguous fear are fascists. If someone is using an ambiguous fear (fear with no basis in fact, a hypothetical about what happened to someone they know as a random example) you have been subjected to fascism. It's that simple.
