It seems you missed this good advice from Roger Leigh:

"Let me begin by stating that I found your reply (and others) to be
rude, unnecessarily aggressive, and lacking in well-reasoned objective
argument. It's poor communication like this which caused me to
unsubscribe from the Debian lists, and also to this list a good while
back (I only read the digest summary on occasion, and rarely
participate). I find it fosters an unfriendly, unpleasant and
unproductive environment which I don't enjoy working in. When you're
doing this type of work as a part-time volunteer, it's extremely
demotivating and disheartening to be treated this way. It would be
unacceptable in a professional setting, and it's equally unacceptable
here. Please do think about what you have written before sending it; it
costs nothing to be nice, even when you are in disagreement with
someone."

PThere is no need to be rude and insulting (often repeatedly). That
goes for everyone of us.
