Why not admit what you already know—that such dislike is a subjective expression of your preferences and not objective "truth" that covers what "everyone should use."
The DA/SA system isn't difficult to master. It isn't getting anyone killed. It is not "inferior," it's just different.
Folks who don't prefer most striker fired systems don't seem to trash them with the fervor that DA/SA is slammed with.
Its like someone started a thread with the specific purpose of trolling. Who said there was "objective truth" involved?
