Outside of the initial stance of wanting to maintain Python 2, I'm amazed at how much of a jerk the Arch distribution maintainer is being to everyone else.
I'm thinking that reactions to this maintainer's answers probably align to which side of the discussion one often find themselves.
Regardless, I find his tone and attitude quite condescending to the Debian maintainer.

They do not extend to anything outside of that, so I don't think it's a broad statement. Just my opinion on his response to the Debian maintainer and other polite requests.
