There is some fairly strong evidence that SSRI use can make certain people more violent. And there appears to be a real causal effect: it's not just that people who already have violent tendencies are more likely to take SSRIs.

We don't know whether this is a significant factor in gun violence.

I'm not sure the study you linked supports that. They found an association between SSRIs and violent crimes, but specifically state they cannot claim a causal link without further study.

Depression in itself increase risk of violence.

Seems like the wrong angle to take, since owning a gun is extremely dangerous for your own safety when you are dealing with severe depression. The risk of successful suicide increases many fold if you have an easy access to a loaded gun.

I'm against gun legislation because of the Second Amendment, and it's obvious meaning along with our historic tradition of the right to bear arms. I support common sense legislation like background searched and red flag laws as partial solutions along with education. We are not against all legislation just the ones that say "no more semis" "no more AR15s" because we know as soon as y'all get those that same reason leads down the road to taking all guns. You're not going to take our guns my friend. We aren't Australia or Europe.

Sure, but I'm not sure how any of what you said relates to my post?

SSRIs can cause depersonalization (a form of dissociation) which can lower the barrier to violence (or self harm). It doesn’t make sense to point to this is a root cause for gun violence generally but it could reasonably be a root cause for an unknown number of mass shootings.
