When we are driving, we are supposed to be aware of the fact that as we drive there is an area in which we cannot see another vehicle. This is the blind spot, and it is why we need to turn our head and look before making a lane change.
Within your own eye there is also a very tiny blind spot. I only notice mine when I have spent too much time reading. I am told this is where the optic nerve connects, but as I always forget to ask my optometrist during my exam, I cannot confirm this.
We do have another blind spot, and this is one that affects our safety. I am still unsure if this blind spot is intentional, or reflexive. What I am sure about is that the behavior can lead to less than ideal circumstances in terms of our own safety.
Put simply, if you resort to the same tactics in your own actions that you are condemning in others, you are gambling that they will not take things to a level that you are not prepared to deal with.
If you truly believe that the actions being taken by someone are wrong, then you leave yourself without a moral leg to stand on when you take those same actions. If bullying is wrong, it is still wrong when you do it. On that same point, it makes you a bully too. If threats of violence are wrong, then it is wrong for you to use such threats.
In our time, people see their own actions as being justified because their motives are righteous.
Here is where this behavior can become problematic; not everyone follows your worldview. There are people who have learned from an early age that violence can settle disagreements in their favor. There are different subcultures that can be very different from yours. A person raised around violence will see violence, threats of violence and other methods of intimidation as tools. Many of the people in our day forget this and do so at their own risk. When you spew vitriol at someone for whom violence is just a tool, violence is what you will probably get, and this will happen without regard to your oh so pure motives. The intimidation rhetoric will work on those who wish to avoid all conflict, but not everyone falls into this category. In spite of all of the attention that the snowflakes get, there are still people who prefer fighting to arguing.
Short form of the above – learn to identify when you are using the tactics you are opposed to, and stop yourself. If it is wrong for them to use those tactics, it is wrong for you as well.
