Wonderfully this is a very good topic from you and I highly agreed with your take and analysis on this.
Anger on one part is natural and it happens when we get offended in some cases,but I must also say that knowing how to managed the anger period too is very essential and I must say your analysis in this topic has moved me alot to talk more now.
It is very essential us to know that people are meant to step on us,but our ability to manage people at times will help in managing situations,anger can be very damaging if it not well taken care of cause it as brings down lot of people and brings an end to Relationship or intimacy that should have last for ever.
You mentioned some ways or steps if I may say that anger can be managed, definitely those ways are purely right,it is better not to talk with an angry mind than talk and scatter things,our words needs to be watched especially when we are angry,what comes out of our mouth is very important and it can be very damaging or disastrous during an angry moment, moving away from the spot where we get annoyed is essential too just like you mentioned cause it will ease our mind from getting more bad or sad about the incident that leads to the anger.
Also we need to know what makes nus happy,which will can think of during an angry moment to ease your mind and don't forget to always.stay away from negative people cause they have a way of bringing out problem from every solution.
Doing away with every bad habit.is also vital,cause this are things that can increase the level of anger in us and can even make it uncontrollable if care is not taken.
Of all having a forgiving spirit just as you have said is important,it will help us go a long way in life,to me I see having a forgiving spirit as an instrument of making peace and a perfect solution to all problem
