It seems that you are the one who doesn't understand democracy. Over 500 MPs voted in 2015 to allow the people to vote whether to leave or remain in the EU. The democratic result was to leave!
This is not about 'normal' Parliamentary procedure where HMG puts a bill to The House and if HM Opposition doesn't like the proposal their role is to oppose it.
Many traditional Labour supporters, particularly in Wales and the North, voted to leave the EU and the sooner we get out the better the outcome will be!

Well said!
