My view is a coldly rational view of establishing the best outcome for me and my family.
In a potentially lethal force situation, the best outcome is coming out without significant harm to us.
In this calculation, I am not concerned with emotions such as a sense of territorial violation. I understand such and have felt it when I was once burgled. However, the property is trivial as compare to the risk of harm, the practical expense of dealing with a lethal shooting in the house, the potential psychological harm and social negative outcomes. I also am not into potential reciprocal altruism to prevent another burglary elsewhere. This is different from saving someone being attacked. That has a different moral context.
I am sure that if I get hurt in an interaction with a burglar - no neighbor or internet participant will contribute one red cent to me.
Thus, I will use lethal force if needed to prevent grievous bodily harm. If I can use various measures to cause the BG to flee - I'll do it. In fact, I've trained in FOF house exercises to hunker down and use command voice to get them to leave.
I note for those who haven't tried it, that when folks went out to engage the bad guys and save their TV, the BGs ambushed them and landed them on their buttocks. Those who hunkered down - with the appropriate long arms - saved the day.
We have sufficient layers of warning and noise such that I will be convinced that someone continuing to advance is a physical threat and then we have the tools for that. Fighting from a defensive position is quite superior in most cases.
Now we see folks arguing that they are predator killers, taking the offensive in the house and the like. They won't let the BG get away. As Dave mentioned, some of that, IMHO, comes from a sense of personal violation and not the rational. I don't think less of you if you don't get yourself killed for your TV but instead hunkered down and called the cops.
However, for some - they don't want to admit that. I have an acquaintance who brags how he clears his house. No training, crappy shot - but he's clearing. I told him that if I were in his house - he probably would be ambushed and dead. Annoyed him.
Think about the overall goal of your home defense plan - is to get the bad guy or is it that you don't get hurt? Your ego doesn't bleed real blood, your body does.
So if you decide to fight - be sure you understand what your goal is.
1. Save self and family from harm
2. Feel good as a warrior
3. Save the neighbors from potential crime.
Why are these your goal? One thing I always say which causes a firestorm, if you choose the altruistic statement - is that really the motive? Theories of altruism suggest that saving the neighbors for some is not that you care about the neighbors but you want their adulation for your heroic effort. Is that really important? If you were truly altruistic, would you actually chip in to support the family of a neighbor killed in a firefight with a burglar. I mean not just giving his family a pound cake and tuna casserole but contributing them for life. I doubt that happens.
Hollering so they go away, if you are in position to do so - makes a lot of sense - if you are truly honest about your decision processes. If you need to fight, then you do. You can reduce the need by not taking foolish ninja risks.
We are armed. The police have been called. Get out

By the way, have the phone line open to the law and the alarm sounding.
