A better way of stating the point without letting the perfect be the enemy of the good and thereby losing sight of the underlying need for further research, would be to say something like the following:
"This is great news. I hope the studies account for x,y, and z, and I look forward to their publication. I also look forward to supporting the legislation this research may make possible and to the safety benefits that stand to be gained. Anyone have any links for ways I can effectively pressure my local legislator and ask them to support even more funding in the future?" That way it's not ambiguous whether the research is supported. If, on the other hand, people just don't want more research, we would all benefit from having that clearly stated at the outset as well.
That being said, the OP’s specific point is also really bad. If gun control leads to reduced deaths, but the reduced deaths are entirely due to reduced suicides (they’re not...but hypothetically), that would still be an argument in favor of gun control, not against.
It may not be a good solution to reducing the mass murder of toddlers, but hey, we won’t know that until we actually do the research on it. Which is the whole point.
(I know that you're just elaborating on what the poster is saying rather than expressing your own views, so treat this as a reply to their comment rather than yours.)
At the risk of sounding grim, if you're looking to commit suicide, a 12-gauge shotgun (very common for bird hunting) is probably your best bet. Nobody's looking to ban those.

Japan & Korea are interesting _because_ they are outliers.
I'm not sure why the Wikipedia page dramatically disagrees with the UK's own stats.
The WHO explanation is here: https://www.who.int/data/gho/indicator-metadata-registry/imr... and their data is here: http://apps.who.int/gho/data/node.main.MHSUICIDEASDR?lang=en
But, France was 12.1 and Ireland 10.9, not much less than the US. I don't think we can conclude from this data that access to firearms accounts for all or even most of the difference.
Imagine a prison, where every prisoner is held within solitary confinement - no contact with others at all. A lot of prisoners commit suicide each year, and the warden needs to reduce this. Is putting every prisoner on suicide watch - removing shoelaces, toilet paper, strong sheets, anything that a prisoner could use to kill themselves - a moral option? After all, it would reduce suicide - sure, the desire for suicide might go up, but no one would be able to act on it, so suicides would go down! But to me... That's just prolonging torture, and that's NOT ok.
We've all got life sentences in this prison, and there's no hope of parole. I personally find life here on Earth to be great! But I can't support preventing people in worse situations from finding a way out. And when you reduce suicide by taking away a way out, instead of providing a better way...
