When a comment starts with "Even ignoring Y, there's also Z" or "Setting aside Y, there's also Z", it shouldn't be read as downplaying Y. It's a way of introducing a secondary issue Z without first needing to write a 1000 word essay that gives due weight to issue Y and any other issues that are more important than Z.

This is useful to do when issue Y is widely known and well-explored elsewhere, but issue Z hasn't received as much attention. It my no means is an attempt to downplay the importance of Y, merely to create a space for conversation about a more niche issue Z.

It's disappointing to see so much attention put into replies attacking the OP for not giving adequate weight to Y, when the very premise of their comment was to create a space to discuss Z.
