Being talked to like I am a child by someone probably younger than me is a bit off putting and doesn't help you get your point across.
Certainly you could have expected that to happen. I would have been surprised if anyone actually had been calm and informative in their responses. One of the benefits of living overseas for about the last 20 years is that unless we go out and dig for it, politics has absolutely no bearing on our day-to-day lives and this is something I am really grateful for. I have found that left or right, the people that do bring it up in public overseas where I have lived tend to be the loudest and most uninformed people you can imagine that are doing the shouting. I have had to tell my lefty and my righty friends to STFU and to stop ruining the ambiance of our shitty dive bar that we were in. They might wake up the guy that is passed out in his own vomit and we can't have that.
I stay completely out of it because I feel as though people get WAY too emotionally attached to these things. Imagine your hardcore political friends and what they could accomplish if they spent that time on literally anything else. That's how I look at it.
I knew you were a progressive and you are handling it a lot better than some of the stuff I see on 9gag. There are a lot of mental health problems in the world, that is for sure.
