"In a way, the contention is true: millions of (fill in subgroup) “feel” under attack, even though no attacks happen."

If they "feel" under attack, it is because the media have been telling them they are under attack, even though there is very little in Trump's actions or rhetoric to support that. You could make a much better case that Jews and Christians and whites are under attack from the left. Anti-Israeli sentiment is mainstream on the left, whereas anti-Jewish sentiment is on the extreme fringes of Trump's support.

Colleges and corporations increasingly sponsor seminars and classes attacking "whiteness," and there is no comparable movement on the right denouncing anyone for the color of their skin.

Christian nominees for political office, and Christian political candidates, are increasingly under attack for their faith, and openly anti-Jewish candidates (Omar, etc.) are being elected as Democrats.

If they "feel" under attack, it is because the media have been telling them they are under attack, ...

That is so, and the situation predates Trump.
