Agreed, the use of fearmongering as a tactic is the exact opposite of helping.
Again, my preference for a course of action is this:
1) We must stop the harm. Allowing the demonstrations, and toxic dialogues on social media to continue enables harm to continue. These things must be stopped.
1a) We must do this while ensuring that the message carried with that action, is one that emphatically states that it is OK to be afraid of other people, or things you do not have experience or familiarity with. because that is a natural reaction (The fear is not something to be exhaulted-- It is something to be overcome, not capitulated to. The fear is natural, but irrational. It is not wrong to feel the fear-- It is wrong to act on the fear.); The prohibition against hate speech is not against the people making it, but against the speech itself, because it foments violence. The goal is to prevent the violence, not to "shut people up." This must be made tremendously clear. (One of the fears is the fear of censure. This fear must not be fed, but the activity must be stopped. This is the best compromise I can offer.)
1b) We must be sure that this happens without invective being hurled around like fecal matter. Again, understanding of the causes of the fear, not condemnation of people for having it, and seeking to be free of it. (The desire to remove the "others" is a person seeking to be free of the fear, but in an ultimately futile fashion; There is no end to "difference"-- the post just gets moved closer and closer inward, until the person has murdered everyone else in paranoid delusional mass murder.) We offer them BETTER ways to become free of that fear. Ones that actually work, and dont involve killing people.
2) We must not fall victim to the same kinds of emotion-based action that causes the problem we seek to address. That is self-defeating at best, and wantonly destructive at worst. If we do get to the point where we must punch people, we will punch people because we have rationally chosen to do so, because all other means have been exhausted. Not because it makes us feel better.
2a) Because of this, our actions need to be as dispassionate as possible, and focus on the active prevention of harm, not the willful causing of it.
3) People feel fear, primarily out of a lack of understanding, knowledge, or familiarity with a topic or subject. Sometimes simple words are not sufficient to foster such understanding. Outreach programs tailored for this purpose have been shown to be effective. Such measures should be encouraged, in a genuinely helpful and welcoming fashion. Application of invective and being verbally abuse is counterproductive.
4) We need to get the Executive back under control. It is under the direction of a leader that has adopted many of the pillars of white nationalism; 'Make America Great Again' calls these kinds of fears, and implicit 'solutions' immediately to mind. It is a harmful message, and needs to stop being proffered. We need to stop trying to deport american citizens, we need to stop trying to concentrate people of different skin colors out of irrational concerns that they are here illegally, or here to cause problems for other citizens. The best way to do that is to remove the current leader; It is easier to remove him, and then correct the system internally, than it is to correct Trump's behavior, and get him to see the light. (He should still be helped to see the light though, just not as president.)
Remember, Alleviate means to "reduce suffering". Placation does not reduce suffering. The people with irrational fears continue to have those fears, and continue to suffer from them. The only real way to alleviate that suffering is to mitigate the causes of their fears.
