troublessplaining
When someone with no understanding of The Troubles in particular, and sectarian paramilitary violence in Northern Ireland in general, feels more qualified to speak on it than someone who experienced it first-hand. Though stereotypically such a person is an English conservative, this could be anyone. Troublessplaining methods include declaring Good Friday to be irrelevant to peace, citing St Andrews as proof GFA no longer applies, and portraying concern over provincial stability as if anti-Brexit propaganda.
Man A: "I've had it with you Remainiacs throwing around meaningless terms like GFA. Britain's been at peace for 20 years, so this is just Project Fear!"
Man B: "Are you really Troublessplaining at me? A bomb went off just last week!"
