Being sarcastic won't lead you to anything, however mentioning what you
just did was constructive, and was clearly non aggressive, thank you.

Now that's not the only reason to fork, and I think I already gave some
good reasons.

Im happy that you fixed bugs, and proved me wrong about the time
counter. I think Im not narrow minded and Im always open for discussion.

Im also thinking that all those flame wars could be avoided and
constructive discussions can really have benefit to both sides.
