Firstly, call it with the insults. If you want a serious discussion, lets have one. But if you are going to assume I am an idiot you are going to have a bad time.
Secondly, please look at this paper

When coal gas was switched away from in the UK, making it much harder to gas oneself to death, the rate of suicide dropped substantially. People stopped being able to use that method and it was not replaced.
This is consistent with what is commonly observed-people have suicidal urges that last for about 15 minutes to half an hour. Outside of that time period they will not try to kill themselves. If you can insert a barrier into that time period then generally that will prevent the suicide. Make suicide take longer and rates drop-that is what that paper shows and that is what people experience.
This is also from my personal first hand experience. It is from my time working for a mental health helpline, and from being the physical barrier to suicides by physically ripping knives from peoples hands and restraining them.
