Contradicting this is that I see a lot of corporate propaganda mixed in with divine claims. Just look at American libertarians. Admitedly, there are many Christians who don't consider them real Christians, but whatever. But persecution complex is also part of the Christian tradition. If you want to know if you're really persecuted, verify if your right to meet at Church was removed (and I don't mean temporarily because of a health crisis). If your books have been banned. If your people are put in jail for owning those books. That's persecution. Apart from that, your claim is false. Religious freedom is part of the US constitution. Of course that does not mean the right for religious people to establish a theocracy or to persecute other people.
Something else is that some are exploiting the legal framework around religion to attempt to pass extremist political propaganda, hate speech and dehumanization narratives. This complicates things. Often a way to determine this is to study propaganda trends, comparing traditional doctrine with the current propaganda. Comparing traditional groups with grassrooting and astroturfing, new extremist cults, etc.
