What this study shows is that a gun is likely the first choice of gun owners who are trying to kill themselves. It cannot determine how much less likely they would have been to kill themselves had they not owned a gun, if at all.
I wonder how many people choose other methods of suicide (Hanging/Drug OD) when they had a gun available.
There is an export feature that will spit out a json file and you can import it to a new instance. It will carry over your subbed communities and blocked accounts. I use it to sync accounts on different instances (My instance can be slow sometimes)
