EU referendum, brexit and the aftermath

I am on holiday in Germany and I was asked by a pharmacist what I thought about Brexit. I had to explain I am deeply upset, embarrassed and ashamed of the result and the attitudes displayed by those who want out. He was expressing disappointment too. His view is that as part of the EU it is a matter of give and take, we help nations when they need it but collectively benefit from our participation.

What this has made me aware of is how downhearted and powerless I feel over our future. In my life I have rarely voted as I consider it farcical that we are expected to chose one person(MP)/party to represent all our views and are meant to trust them with this for four years. I actually voted in the last general election, Brexit and a by election and did not feel the satisfaction of having contributed to the greater good as I watched the aresoles take over and run the show.

It appears there is no real opposition and I want to know what can be done to attempt to influence the abominable situation. It is easy to whinge on here in our little echo chamber. What action can we make to try to take, what stand can we make to express that we don't want the confused and deceived "will of the people" to be enacted?

I don't want to look back in years to come and realise all I did to try and stop this gradual descent into bigotry and descrimination was to post on the fixie skidder forum. But currently have no clue as to what to do.
