Perfectly reasonable.I always provide references/links. What ends up happening is that I provide it to the person I'm responding to and then others ask for references later in the thread when they respond to me.
I'm not going to repeatedly post the same info.
If it's important enough for someone to refute what I'm saying then they should at least follow along the thread and not ask for stuff that has already been provided.
Is that not reasonable?
This isn't an attack.
I am pointing out that I don't expect people to provide useful links, you included.
I am always happily surprised when they do.
