I actually see where you're coming from.
I've visited a few rival forums, mainly from links on here.
I've nearly joined, if only to correct a few over inflated mistruths.
But the thing i found was that all fans just want a place to hang out and console each other about how good/bad their team is. Very few want to talk real football like you would face to face with rival fans.
So it leads to fake news being regurgitated a real facts.
Ultimately, you will never win. Being a member of a rival forum is just pointless.
You can point out facts out all day long and somebody will try and shoot you down. Your differing opinion will always be seen as wumming because you will never gain trust. Proper blues on here are routinely called rags for ever daring to give an unpopular/opposing view.
Try winding people up and you will just get binned.
Honestly, you would be better spending your time elsewhere...
