You jumped in to an 'exchange of views' on the effect of Brexit on the UK fishing industry, and included a collective dig at "little EUers". So whilst you may not have added a personal contribution to the debate, your interjection left you open to inclusion in the 'brainwashed Brexiteers' group.
The point that was being made is that despite what the jihadists might preach, the UK Government has less control over UK, and particularly English, fishing than might be expected.
