So where do you think this no platforming of liberals is taking place?
It’s not happening in the media. It’s not happening on social media. It’s not happening on the campus. It’s not happening in the office.
All you’ve actually been able to identify if _some_ conservative Christian colleges (you haven’t substantiated that, but I’ll accepts it’s probably true to some extent), and the football pitch (which isn’t a political forum to begin with). As I said, you want to have your cake and eat it too.
Edit: it looks like you've been using HN primarily for political or ideological battle. The site guidelines explicitly ask you not to do that, and point out that we ban accounts that do. We have to, because flamewars consume everything if you let them. Please (re-)read https://news.ycombinator.com/newsguidelines.html and use the site as intended from now on.
