Not if they are unlawful.As the thread is about Brexit then it is legitimate to include all strands of opinion relating to Brexit.
And bear in mind that the corollary of that is that it is legitimate to include you being utterly buried under a torrent of vitriolic abuse telling you just how vile and primitive and unacceptable your opinions are every time you stick your sorry defective head above the parapet. Ideally what should happen every time you do it is that the post count in the topic immediately shoots up to the hundreds, with every one saying what a disgusting and shameful splot of scum not fit to be a member of society you are.
