A phrase used in Britain to denote the belief by certain mouthy
activist groups that British society as a whole discriminates against minorities. These groups can represent ethnic, religious or other minorities, or they could just be professional
bleeding hearts, but they all promote the same bullshit; namely that an action taken by society against a member of a minority group will automatically infringe their human rights. This has led to the ridiculous situation where members of a minority groups get away with acts that would see a member of the largely silent majority jailed. This is due to greedy lawyers and waste of space organisations who mindlessly support these people, often at huge cost to the British taxpayer.
Unfortunately minority pressure groups like Liberty, professional
bleeding hearts and all the other wasters who are BVA have pressured politicians into the belief that this is a vote winner. In fact, if politicians merely gave the matter a few minutes thought (there's an oxymoron politician and thought) they would realise that they are placing the needs of a minority above those of the majority. Effectively they have been brainwashed into a Minority Mentality.
Certain pressure groups are demanding that Shamima Begum, a member of
Islamic State who has had her British citizenship revoked, should have it reinstated and
should be allowed to return to Britain. A really unpleasant example of
the Minority Mentality at work.
