I'm not going to comment on the rest because they are your views but what I can offer, from my experience in the NHS, is that the above is a poor and flawed judgment on the situation. It certainly isn't "sensible".
Waiting times in A&E, waiting times to be seen after your referral, operation cancellations, available beds, nursing and doctor staffing and many, many more critical aspects are at their worst levels in most of our lifetimes across the board.
The NHS will forever need more funding, it's the nature of the beast. The older we live, the more reliance we have on the service and the more expense we therefore require. But to dismiss the Conservatives actions and decision making on the way to this crisis is an inherently flawed judgment that requires people to speak against that.
Nobody is saying Labour will get it right but they're promising to do a damn sight more in trying to fix things than any recent Conservative government has.
I suspect you'll be the first person to criticise the NHS when they can't deal with a problem that you will inevitably have in life at some point. Instead of getting angry at the staff, the process and the results, remember that you voted to maintain the status quo and against a party trying to lead on accountable change and improvement.
