Here: https://www.redcafe.net/threads/eu-referendum-uk-residents-vote-today.404633/What's the general Brexit sentiment on redcafe then?
I assuming there was poll at some point.
Prior to the vote:
Should the United Kingdom remain a member of the EU?
Yes: 482 vote(s) 73.8%
No: 171 vote(s) 26.2%

After the vote:
How did you vote to this: Should the United Kingdom remain a member of the EU or leave the EU?
Remain a member of the European Union: 321 vote(s) 75.5%
Leave the European Union: 80 vote(s) 18.8%
Spoiled ballot: 24 vote(s) 5.6%
As you can see from that as well as the 2015 and 2017 GE threads, the caf is generally left leaning and not indicative of what the general public think.
