There was only 1-2 pro-leave people in the thread posting from a position of reason and making actual valid points anyhow - the rest were little better than CTers posting rubbish such as the UK being forced to adopt the Euro by 2021 and repeating the same nonsense despite being shown that it factually wasn't the case and it doesn't take 2 seconds to google and find out that the UK and Denmark have secured exemptions from the policies that are coming in for new entrants to the EU to have a plan for adopting the Euro after that time and so on along the same lines for other matters.
The way some pro-leave posters in that thread are treated is inconsistent with moderating elsewhere to be fair but at the same time I'm not sure where the balance lies between opinion and trolling when it comes to their posts.
EDIT: Have links for threads on other forums? I've only ever really seen polarised leave or remain echo chambers on most other forums or alternatively full on vitriol from both sides and nowhere with proper back and forth discussion.
The main forum I'm a member of elsewhere is invite only now (bst-secure.com) or casually on another site regarding my car make/model.
I waded into the 9/11 CT thread as an 'agnostic' and got a decent flaming for not denouncing members here who are CT inclined, until I revealed my sources as Ron Unz and Paul Craig Roberts, persons of impressive status in the US who are saying all the wrong things as far as US MSM is concerned, then there was a backing off and not going mental at me, which was rare but nice
Those two sources also had a decent amount to say on Brexit, and they were my primary sources during the referendum, rather than TV or Facebook.
A few years on, and it seems the leave case needs reinvigorating after being so dormant. We thought we'd won - we hadn't. The remain campaign has been subtley going on ever since we dropped our guard hearing that we'd won, and is constantly under the peril of being cancelled, and strangely enough we're quite rusty. Instead the remainers have been polishing up all these years on how to tell the world Brexiteeres are foolish traitor subhumans regarding how we voted in 2016. I suspect the time is coming where the Brexit voters are going to wake up and advise many to put a sock in it, like we did back in the original referendum, as we apparently need to go again rather than rest on our laurels having won the first referendum.
