We did agree to be in the EU.
In any case, I trust you'll never vote again or protest against any voting outcomes that you disagree with as you seem to think that once a vote has been held, the outcome can never be disagreed with.
I don't expect everyone to be happy about the outcome of votes, but I do expect outcomes to be respected.
I'm not opposed to decisions being overturned, but I don't think it's right to re-run a vote right after it has been carried out. We haven't even left the EU yet. At some point after we've left the EU, perhaps there will be grounds to take another look at membership of the EU. But not straight away.
I want as many people as possible to participate in elections and referendums (even if I disagree with them), because I want everyone's voice to be heard. That's what it means to live in a democracy. And so I certainly intend to continue voting.
