I am on the verge of cancelling our family NT membership, after almost 15 years. The two reasons are; the abysmal shambles they made of access over lock-down - poor booking service, limited capacity at huge sites, inflexible admissions policy. The second, is the rising feeling that we, the ordinary members, are something of an embarrassment - the increasingly patronising and politised virtue signalling, the lack of real critical thinking and smug assumption that the members want the NT to be associated with marxist political movements. The leadership seems to have been Common Purposed. The lecture over slavery and the Empire is a crossing the rubicon moment. A healthy critical debate (plantation slave exploitation v Wilberforce and the West Africa Squadron) would have been a far more erudite approach.
