I agree with most of the sentiments expressed here: stop being pompous and viewing yourself as better than others. Having high standards doesn't give you the right to judge others; it provides a "measuring rod" for what you are willing to tolerate and establishes the foundation of your personal behavior. I have very high standards, but I don't have the right to force them upon anyone else. As a result, if someone is behaving in an intolerable fashion from my perspective, I have the choice to avoid future interaction with them or to refuse to conduct myself in a similar manner when I'm forced to be around them. If the opportunity presents itself, I can respectfully share how their behavior offends or is different than mine, but they have the right to either change their behavior or tell me to "kiss where the sun doesn't shine." At that point, I once again have the right to accept their refusal to change or minimize my interaction with them.
I am forced for professional reasons to interact with people who are blatantly profane (I don't curse), exhibit continual crude behavior, etc., and without me saying a word (except in extreme circumstances) or demonstrating my disapproval via my body language, they began excusing themselves when cursing around me or exhibiting some of the behaviors which they noticed I don't involve myself in although I informed them that they owe me no apology. One of the main reasons why they've adjusted their behavior around me is that they know I truly care about them and treat them with respect despite their standards being different or lower than mine instead of me acting critical toward them. I give them the grace to be themselves without my scrutiny and expect the same since I know I have areas where I'm imperfect (for example, I can be abrupt, sarcastic and a know-it-all).
Finally, would you want to be under the same critical inspection over your own life than you subject others to continually? You might be surprised to learn that if you express your critical observations of others that they would quickly respond with similar and possibly more flaws in your personality (including being judgmental, condescending and dismissive) than you perceived in them.
