In SVN, "merging" is a bad, scary, no good word. In Git/Mercurial it's an everyday operation that happens so seamlessly 90% of the time that you don't even notice. The other 10% of the time, you have great tools (i.e. 3-way merge tools) that make it easy to reconcile conflicting changes.
Agreed. Amazing how much the right tool can change habits - for the extremely better. It has barely occurred to me that people might struggle with merges (at least, small feature merges) anymore.
Switch to git at a minimum, if possible.
