"...but over 17 million of us voted to leave, that must count for something..."
No emmie. The 16m who voted to remain are far more important. This is the only thing politicians have been asked to do in 40 years (other than rubber stamp EU directives) and, unsurprisingly, they've failed miserably.
Of course it'd be betrayal; it's the old EU trick of dismissing the decision, and working on changing sufficient minds by whatever means necessary in order to get a different result next. The government got the result, it's one responsibility from that is to implement it properly; not pretend to, nor to try to get a different result, one they approve of and would be happy to implement.
You're welcome to pretend that "the losers" would have kept quiet, but Farage already admitted that wasn't the case. And, besides, why should you have kept quiet? You all argued passionately that staying in the EU was awful -- disastrous, even -- for Britain. Why should you stop arguing that, just because you lost one vote, on one day?
No, the Brexiteers would never have shut up. And, more importantly, they *should* never have shut up.
Not shut up but neither yell either, but work towards a date, after a suitable interval, when experience could change the prevailing public opinion naturally, not via fear stories about what might happen. Then it'd be time to reconsider.
It's perfectly ok to support your party and leader when on the spot, then go spend time thinking whether there is a better option. Implying that, that's unprincipled is unfair and incorrect.
It's no time to reconsider at all when one hasn't even attempted to prove one's decision correct. Flip-floppers deserve little respect as they can't make up their mind. We did all the consideration necessary before finding the courage to vote for change.
