One way that I see not to be fooled or intimidated is learn to be aware of when you’re doing it, or tempted to do it, yourself. Another way is by learning to do your own research. The most consequential way might be to learn to satisfy your psychological and social needs without any admiration or approval from anyone, and everyone with everyone around you disparaging and vilifying you. People are fooled and intimidated by their own factions and social circles far more than by anyone or anything else.
it might help sometimes to be aware of some specific tactics that are used, consciously or unconsciously. One specifically Baha’i tactic is Baha’is quoting from Baha’i writings about unity or about ignoring people’s faults if another Baha’i objects to anything that they’re saying or doing. They obviously don’t think that it’s always wrong for any Baha’i to object to what any other Baha’is are doing, because that’s exactly what they’re doing to you, slapping your hand with those quotes. They’re just using those quotes to shame you into silence about what they’re doing, or submission to it. Sometimes they might think of themselves as being open to constructive criticism, or even welcoming it, but if so they don’t see any possibility of it ever coming from other Baha’is.
I’ve seen the same tactic used by Christians, using what Jesus says about not judging people. There might be similar tactics used in other religions.
