You may now all curse me for my moral torpitude

To paraphrase a truly nasty bit of jingoism: "my countryman! My countryman right or wrong, but always my countryman!" The preceding rant inspired not by patriotism (yrch!) but by a desire to obfuscate my own shockingly inconsistent stand on the issue under discussion. The only one of your listed examples I cling to is "data" as a plural, apart from very occasional flirtations with curriculae, as curriculums is just plain ugly to say.
