Thanks for your replies...
They make clear to me I didn't break a rule or wrote something wrong. It's only because someone (and maybe some other) think it's better to change it.
Of course, I have a different opinion. I wouldn't had written this if not.
To me, the point is not to know which pov is the best. The point is to know if, in this place, people think they've got the right to rule others with their opinions. Rules are great because they allow various people and ideas to coexist peacefully. And adversely, when people start to enforce their opinions as if they were rules, diversity vanishes and conflicts arise.
Maybe people here don't really price diversity and peace. I will not advocate or ask anything to change. Just leave quietly if this is the case.
EDIT:
@Jacob Vlijm: I'm not taking this personally. I posted here to know if I made a mistake (maybe these kind of comments are forbidden and I know not). Now, I too regularly say to myself: "hey, the post is even more readable without this line", but I don't rush on it. I first ask myself if this modification can be prove to be better, using rules and facts. Spelling mistakes can be checked against a dictionary, performances and solutions can be tested, and so on. If not, it's an opinion matter, and then I politely suggest or more often shut up. Who cares about my opinions ?
I don't do this because I'm a shining virtuous man, but because it's effective. I avoid offending people without good reasons, and often, thinking twice on things which look obvious to me at first glance show me I missed something of their complexity or their merit. Last but not least, this often leads me to focus on the main goal, not on trifles.
And here what is the goal ? To answer questions ? Correct ? Now take a look at the post: my first reply was given some hours after the OP. That's because a fair amount of people take care of freshly posted questions. No need to join them, so I roam some pages in the past to find if I can help there. I found this fairly simple question, 99% chances my reply will work. Turning into a full answer, and less than a minute after, muru's edit came. Muru is not a newbie and I bet he could have replied himself before me. So what ? There's a lot of edit work here, and my question is: is this not detrimental to the real goal which is to give answers ?
@muru: don't feel confused, and no, I would not rollback your changes because it would be mirroring exactly what you did editing my reply. So what ? You could then restore your edit, and... I guess we're both intelligent enough to give up at some point, but there's no real reason for this conflict to stop.
Friendly,
