Staying with your own practice, and focusing on what you are doing rather than what other people are doing will allow you to accomplish much more in your practice. You will find yourself less distracted, less angry, and more true to yourself. Just because you come across something, or interact with something that's you find strange, difference, or wrong does not mean you have to dedicate your own effort in time to try to correct it, or make it up to your standard. Simply allowed to go by because it probably isn't as big a deal as you think it is, and does not affect you in the slightest. Allow yourself to channel that energy into something more productive that can allow you to better yourself, and your practice rather than attacking, belittling, or attempting to change someone, or something else's practice, or understanding.
