Assuming the invaders have a just reason and are more in line with my ideology...

What are the invaders there for?

"Just reason" is subjective

I mean, it's a case to case basis

For example, let's just go to the nazi germany circa 1945

Supposing I'm...

Invaders are almost there to spread their influence

a lesbian, communist german

Who's somehow managed to make it this far

Should I defend the german homeland, the german people, even though if I did so, I'd likely be persecuted after making my effort

A communist doesn't value ethic blood so no

^

eh, fine

just a lesbian german

there we go

Again the subject of debate has to be WHAT are the right principles

I wouldn't be killed, mind you

And why

Communists are inherently internationalist, aside from some fringe movements like National Bolshevism

Still, I'm asking in your set of beliefs

Even then

Should I?

Would it be the "right" thing to do?

Even though my nation directly violates all my personal beliefs

Is morality subjective

"Should I defend the german homeland, the german people, even though if I did so, I'd likely be persecuted after making my effort"

This is a bit irrelevant, but to you would actually probably be spared

The answer to that question determines the answer to yours

Hitler spared Jews and also let blacks fight in his army

*some Jews

But it's irrelevant

If morality is objective then your personal beliefs are irrelevant to what is right

The jews he spared were generally only used in administration roles in aiding the holocaust

Morality is subjective

I'm not interested in debating Hitler right now. It has nothing to do with principles

I do agree it's subjective, though

@The Big Oof intersting, then why on earth do you oppose Moth?

I'm merely questioning your morality

I can understand questioning the morality of others, even if it is subjective

If its subjective then the lesbian should follow her personal beliefs

Since to her this is moral and there's no objective morality

That's what would happen
