I can’t provide any universal answer to that. For some, it’s a threat to their families. For others, it may be a threat to their faith or their principles (although such threats tend to be amorphous). Others may take a stand for profit or other self benefit.
Whatever line we draw as individuals, the time is fast approaching when we will need to decide.
We all know, or think we know, what we want, but so far no one knows how to get it done...for the last 2k yrs or so.
Why do you think the time is fast approaching and what are the lines that are to be drawn?
