Quitting a club

Where some trade association of … drum roll … chartered (sic) IS auditors declared Cybersecurity is becoming an ever bigger problem. An IS auditor should need to keep informed of the latest developments as an argument to join in some CYBER ARRGHHH! lecture,
one better leaves. I did.

Sure, I’m member of some other, global, of the same trade and tricks one might say. But to list the other arguments to quit the local (i.e., Dutch; could have characterised them as ‘provincial’ but why) one, would take ten pages (yes I have them, spelled out including various legal trespassing of the vilest kind, far from complete after some this-years developments within the club…) and I don’t want to bother you with the water under the bridge.
And sure, I re-joined yet another trade association. And try to contribute in another way, as yet not yet disclosed. And #ditchcyber.

But I’m unsure about my discretion in leaving (behind the hopeless) and would be curious about your best advice when and how (that’s two) to quit a club. Thoughts?
