Dear Grammar Nazi,
I understand that it can be frustrating when people fail at their attempts to communicate with you. And indeed, whenever you disagree with that person, the temptation to use a lack of communicative skill as a means of personal attack can be nearly impossible to refuse. However, things have clearly gone too far.
It is entirely fine to end a sentence in a preposition. In fact, this "rule" was never actually a part of English, even as far back as Old English, but was imported from the French syntax, which needless to say is largely incompatible with all the epochs of our language. Also, do not admonish people for using split infinitives, as no one can really see how the split could obscure meaning. "To boldly go where no man has gone before," is a perfectly legitimate sentence.
Truth be told, Edgar Allen Poe often began sentences with the word "and," and even began a paragraph in The Masque of the Red Death with the word "but." I also personally know published authors who still have no idea how to properly use the semi-colon, and avoid it entirely.
What is at stake here is not the future of the English Language, rather, your own sense of superiority. To use strict grammar as your own personal shibboleth against those you deem unworthy of your attention. What matters most is clarity of meaning and intent, not arbitrary rules invented long after-the-fact in an attempt to explain why a language works.
Sincerely,
Ryan
