When it comes to the world and everyones different views, there should be no ignorance. Nor should there be conscientious stupidity. This is because both of these tools are powerful enough to cause destruction. Feeding off bad energy and starting mixed emotions. So i agree that people should know what's right because they never know who they'll meet, how they'll react, or what they can do for you. Say a woman/man comes in your presents.
They accidentally bump in to you. How do you react not know who they are? They could be a Doctor, a Lawyer, or even a Director. On the other hand they could be a robber, a killer, or a terrorist. So how do you act in a manner of disrespect to a person that you dont know. Also, You dont What they are going through and are unprepared for their reaction.
A person can react in over millions of ways by how you say, move, or apporach them. So why give them more reasons to want to fight, hurt, or even kill someone for you being disrespectful. They could cause harm to others, to themselves, or even you. So do you wanna be the reason people die because you wanted to be disrespectful? Is it fair to the others to suffer cause of you. Now think if that is someone in the office you walk in.
They see you and remeber there incounter with you that one time. If you are there for a job and now that stanger holds your chances of the job in their hand. If you were respectable in the crossing of paths he may lean in your favor. On the other side of the coin, if you acted in a disrespectful manner they wont listen to any thing you have to say. Now you are out of a job because you showed no respect.
As you can see i agree because you never know who you'll meet, how they'll react, or what they can do for you. It take nothing but a little respect and you can go far. Not saying let people walk over you, but don't just jump on the first reaction. Think because you never no what can happen from being respectful. So try it next time you fell like snapping.
