Why are you engaged in this debate when you live elsewhere?
Seriously - do you give a fuck what I think about BREXIT? I sure hope not because even I don't give a fuck about it.
I don't think it's such a terrible idea to share perspectives and information. Just because someone lives in another country doesn't mean they can't care about issues we deal with. I'm sure there's been at least one issue outside of the US that's caught your attention and that you have thoughts to share on... At least one.
