I have played pathfinder and other skill heavy systems, and they are valid fun methods of play.
I prefer AD&D and other skill-light systems for a variety of reasons.
All role-playing games use conflict resolution methods.
Some of these conflict resolution methods could be considered skills.
There is nothing inherently right or wrong about skills.
And finally, this:
Skills can be used as a tool to avoid DM Tyranny (i.e. I rolled it, you have to let me!), just as easily as skills can be used as a tool to enforce DM Tyranny (i.e. you didn't roll high enough, you aren't allowed!)
Rules will not prevent people from being jerks. A skill system is zero protection for players - A GM can set skill DC's arbitrarily high to ensure failure. The rules system is no defense.
