I endorse the vast majority of the post. Lying in most of those circumstances seems like an entirely appropriate choice, particularly to people you do not respect enough to expect them to respond acceptably to truth. Telling people the truth when those people are going to screw you over is unethical (according to my intuitive morality which seems to consider 'being a dumbass" abhorrent.)

If you're highly averse to lying, I'm not going to spend a lot of time trying to convince you to tell white lies more often. But I will implore you to do one thing: accept other people's right to lie to you.

People have the right to lie. People do not have the right to lie without consequences. I suggest people respond to being lied to in whatever way best meets their own goals and best facilitates their own wellbeing. Those adept at navigating a sea of social bullshit and deception may choose to never treat lies as defections or provide any negative consequences. Those less adept at that kind of thinking may be better served by being less tolerant of lies from those with a given degree of closeness to them.

I implore you to respect other's right to treat lies, liars, and you in whatever way suits them.

On the other hand, if we ever meet in person, I hope you realize I might lie to you. Failure to realize a statement could be a white lie can create some terribly awkward situations.

I personally assume people lie all the time (or, more technically, I assume they bullshit all the time). However, speaking about other people you may encounter I hope you realize that some people do not interpret lies the way you hope. Failure to realize that your lie will create some terribly awkward situations is your behaviour and your consequence (as well as a consequence to the non-savvy recipient). As the person who is (presumably) more socially aware of the two parties and the person who has analysed the subject more you are going to be better equipped to adapt. So either don't lie to people when it's going to create terribly awkward situations or avoid talking to people when you expect your preferred behavioural pattern will not work with them (eg. based on apparently clumsy body language).

As is the case with all notions about how people ought to interact with each other, if you attempt to enforce your own standards and don't adapt to the person you are interacting with you can expect things to go poorly. This applies to lying averse people interacting with liars. It applies to liars interacting with the lie-averse. It applies to 'Guess culture' people forcing their behaviour or interpretations on non-guessers and the reverse.

The most notable failure pattern that I observe is that of a wilful, stubborn, insistence that consequences are responsibility of the other party because "my" way is the naturally right way for the universe to be. A psychological disposition based precommitment not to swerve in a game of chicken.
