@Koda94,
Not sure if any argument is going to convince you, but firearms are used all the time to prevent a crime without ever having to fire a shot. Just read American rifleman for plenty of examples. I'm not pulling the trigger unless I absolutely have to. It doesn't mean I'm not prepared to do so if I have to.
You can say the intimidation factor is a total myth. You can argue that batteries fail. My question is what is the downside to having an ADDITIONAL tool at your disposal? You mentioned giving the bad guy something to shoot at. If this is some sort of ambush situation, possibly, but simply taking pressure off the switch will turn off the light/laser. As for hunting for a laser dot, my laser is adjusted to land exactly on point of impact, or basically, right where my sights line up. For point shooting, it is a great confirmation of point of aim.
To each his own I guess.
