Politics and religion cause a lot of arguments.
I don't think anyone will bother if you simply stateĀ - "I support the XX party", but if you start putting on long spiels of propaganda, then they will object!
For myself, I voted against the Common Market, I voted against the EU, and I voted for OUT of the EU. (not that it did any good!)
IF we have a candidate for Rupert Lowe's new party, I'll vote for that person.
If we don't have someone standing, I'll not be voting for the Lab or the Con. I'll have to choose from the best of the rest.
if you are calm and collected when all about you are going berserk - you've missed something important!
