My point was that your use of "bringing together" in the context of putting it as Columbus achievement when we all know what happened and what he did when he got there was insensitive. You realise that there are people still living under the consequences of that? People have been still been dying because of it in the 90s. It is not some small event that happened a while ago but a huge continent scale massive event that is still reverberating nowadays. In deference to people who are still alive and affected by it, "Connecting" is a neutral term that better conveys what happened without having to add your own moral viewpoint on whether what he did was good.
It was horrific and it would be nice if you acknowledged that the same way you acknowledge the systematic horrors that certain countries did in a certain large scale war the previous century even if science and lots of countries progressed socially, ethical and technologically as a result of it.
