If I had to delete an app every time I see something I politically disagree with I would have no need for a smartphone.
I felt terrified by what I saw, quite literally sickened by it. I closed my phone completely and struggled to sleep afterwards. It took me three days and some conversations with my family before I could open the app again just to delete my account.
I'm not just taking some moral stand against Instagram by leaving it for publishing views that differ to mine, I'm simply too disgusted to ever open it again, the thought of having an app like that on my phone makes me queasy.
