It's high time that Foreign Affairs Canada started issuing warnings against travelling to the US. You are likely to be subjected to patently unreasonable search and seizure at the border, so the prudent traveller will not travel with any electronic device with any personal information whatsoever recorded on it, and will anonymize all social media accounts before travelling. Once inside the US, you are at risk of being shot by a policeperson simply because they imagine you are acting in a possibly threatening manner. You may at any time be accused of some form of terrorist connection and imprisoned for long periods on the flimsiest evidence. All in all, the US has become a very good place to avoid.
