Not everyone in organisations nor political parties we support will be perfect Ian. Abd as you say, sadly , some dickheads are drawn to bikes (the worst ones often on quads in urban settings, cos they dont want to have to pass a bike test).
An important point that MAG has recently been pushing is exactly the one you make about club members like yourself who are also BMF/MAG members through their clubs. Turns out - big surprise to me - that MAG membership through a club gets literally pennies per member to MAG!! From a point of paying fir politicsl lobbying (or say an air fare to a Transport Scotland meeting), it isnt very helpful...but all those club me bers feel they've done their bit.
I would again seriously ask everyone on two wheel to think about being an individusl member of MAG, BMF, LARA, TRF.
MAG is £27 individual membership, the magazine has become pretty good (it's as big as say Ride), and if you go to the right Yorkshire rallies, you get free beer tokens to their very cheap bars.
But mist importantly, without cash coming in, the govt get to do what they want.
Cycling isn't being promoted just cos its cheap(-ish) and healthy (except for RTA rate). They have lots of folk onside, and lots of me bers of CTC, SPOKES, and lots of other clubs. (and I say that as an occasional cyclist, in fact I'm about to cycle to Screwfix).
