I've been pondering it too but I didn't feel qualified to try and define what the Labour Party of today actually stands for. Perhaps it is an impossible ask but I like your take on it.
I can answer the question about why I waste my time with the PC though. Some of the Cllr's do considerable and admirable work in the community, some, I'm not quite sure what they do or why they do it. For myself, I hate wastefulness and squander of tax payers money so my personal cause celeb within the parish is expose the ineptitude, inefficiency and incompetence of PC decisions as relates to scandalous waste of tax payers money - that's my 'service' to the tax payer and it's a thankless, uphill struggle against the inequities of long established cronyism within the PC and deep rooted public mistrust (with due cause) of Local Authority.
If anyone is interested, I created a Facebook page (to the immense displeasure of the PC) which can be viewed here:
https://www.facebook.com/StCleer/?ref=bookmarks
For a relatively small village / parish it currently has 161 "likes" and 171 "follows" which far outstrips the "official" PC facebook page and that of the Ward Councillor. It's made me no friends within the PC though, within the past couple of months there have been attempted harassment charges brought to D&C Police (dismissed out of hand), Code of Conduct Complaint to the LA (partially upheld but a shallow victory since I consider it to be meaningless), an attempt at an aggressive take over of the Facebook page by the PC (you can imagine my reaction to that), an article in the parish rag due this week and threats of legal action from the PC's solicitor. It's ruffling a few feathers and making some people very uncomfortable - that is my measure of success and the harder they try to suppress the more I'll bring into the public domain. If the cretinous incompetence of some of the decisions made at this local level are multiplied by the number of PCs in the land, then multiplied again by LA town, district, unitary areas, then multiplied again at the party political level, electoral wards and national government level, and then multiplied again by international organisations such as the EU, NATO, UN, etc... The amount of money being pissed up the wall would be truly, eye-wateringly, unbelievably staggering.
That's why I do my bit and for as long as I'm getting the clicks and support via the FB page I'll continue. Hope all well up there Mr ?and you're on the mend after the Heath.... ?
