Political discourse you'd be able to discuss like a professional, i.e. EU Parliament.
I'd mention the UK's House of Commons but they might go a bit far referring to the opposition speakers as "The Right Honourable Gentlemen/Lady"... and the jeering.
Saying what you want, but not with language that is offensive. There's a difference between "There's too much immigration which is affecting local employment" and "The fucking foreigners are taking all the jobs, the cunts". Both say the same thing, but at least with the former you can politely debate it without getting immediately angry.
