You can't attack another user like this here, and we ban accounts that do, so please don't do it again.

Edit: it looks like your account has posted over a dozen of these hostile replies to the same user. This borders on harassment and certainly is not a good way to participate in the community. Please stop doing this and focus instead of using HN as intended: to explore things that you're personally curious about, not to prosecute agendas.
Edit 2: attacking other users, as you did at https://news.ycombinator.com/item?id=49086538, is obviously not ok either. If you keep breaking HN's rules, we are going to ban you, so please review https://news.ycombinator.com/newsguidelines.html and stick to them going forward.
