Can you not see that arguments against the new and for the old are meaningless?

As opposed to arguing against the old and for the new? What are you accomplishing here that's turned out any more fruitful than the posts of those you belittle? You're trying to extinguish a fire with gasoline. You're only expanding quarrels. You can't help with people's frustration when a) you're not its source and have no influence over that source b) act so aggressively you become a new source of argument and frustration yourself.

Maybe in an alternate dimension you can solve arguments by making everyone see things your way which simply requires you to describe your perspective, but as you've surely found out by now it doesn't work in this one.

I don't see how any of this helps the Opera team you're trying to defend so much. So if you really want to support them, try something else, this isn't working.
