There will never be another human being good enough to decide what other people can say or hear. I can’t share your lack of concern for politeness though. I think it’s definitely something to strive for. I have a complaint with the “self defense” community because they emphasize “awareness” and “brutality” over less emotionally charged concepts like leverage and athleticism. Over time focusing on evil things seems to weaken people by making them more aggressive and less healthy. Exercise should relieve stress and make the body less susceptible to harm. People who watch cnn all day and get worked up over it are running a terrible risk. Reading angry articles on medium all day might be deadly if it wasn’t me debated with humor. I wasn’t thinking of you in particular when I pointed this out, nothing could have been further from my mind.
