It's less to do with any particular individuals and much more to do with the political culture as a whole.
For instance, at the last year's Saxony Day in Schwarzenberg, there was a line of stands for the political parties, in front of which there was a queue of punters wanting to speak with them about their policies. The usual suspects were all present (CDU, SPD, FDP, The Left, The Alliance/Greens) along with Alternative for Germany and some others. The whole atmosphere was grown-up, friendly and non-tribal, with people leaving the sausage & beer stands to come and talk to politicians. The people I spoke to were thinking about what things they wanted to happen rather than which particular troop they hated the least.
It was a delight to be honest. And most remarkable for the complete absence of class-politics.
But if we were to leave the EU, surely I'd cease to be an EU citizen?
In which case, in order to remain an EU citizen, I'd need to become a citizen of an EU member-state.
